Summary
Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by leveraging an untrusted web application.

Summary
Red Hat Security Advisory: tomcat5 security and bug fix update
Notes
Topic
Updated tomcat5 packages that fix multiple security issues and two bugs are
now available for JBoss Enterprise Web Server 1.0.2 for Red Hat
Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.
JBoss Enterprise Web Server includes the Tomcat Native library, providing
Apache Portable Runtime (APR) support for Tomcat. References in this text
to APR refer to the Tomcat Native implementation, not any other apr
package.
This update includes bug fixes as documented in JBPAPP-4873 and
JBPAPP-6133. It also resolves the following security issues:
Multiple flaws were found in the way Tomcat handled HTTP DIGEST
authentication. These flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063,
CVE-2011-5064)
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw. (CVE-2011-3190)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause Tomcat to use an excessive amount of CPU time by sending an HTTP
request with a large number of parameters whose names map to the same hash
value. This update introduces a limit on the number of parameters processed
per request to mitigate this issue. The default limit is 512 for parameters
and 128 for headers. These defaults can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2011-4858)
It was found that Tomcat did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make Tomcat use
an excessive amount of CPU time by sending an HTTP request containing a
large number of parameters or large parameter values. This update
introduces limits on the number of parameters and headers processed per
request to address this issue. Refer to the CVE-2011-4858 description for
information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception
occurred when creating a new user with a JMX client, that user's password
was logged to Tomcat log files. Note: By default, only administrators have
access to such log files. (CVE-2011-2204)
A flaw was found in the way Tomcat handled sendfile request attributes
when using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious
web application running on a Tomcat instance could use this flaw to bypass
security manager restrictions and gain access to files it would otherwise
be unable to access, or possibly terminate the Java Virtual Machine (JVM).
The HTTP NIO connector is used by default in JBoss Enterprise Web Server.
(CVE-2011-2526)
Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the
Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges
Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4858.
Users of Tomcat should upgrade to these updated packages, which resolve
these issues. Tomcat must be restarted for this update to take effect.

This update\nintroduces limits on the number of parameters and headers processed per\nrequest to address this issue. Refer to the CVE-2011-4858 description for\ninformation about the org.apache.tomcat.util.http.Parameters.MAX_COUNT and\norg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.\n(CVE-2012-0022)\n\nA flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception\noccurred when creating a new user with a JMX client, that user\u0027s password\nwas logged to Tomcat log files. Note: By default, only administrators have\naccess to such log files. (CVE-2011-2204)\n\nA flaw was found in the way Tomcat handled sendfile request attributes\nwhen using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious\nweb application running on a Tomcat instance could use this flaw to bypass\nsecurity manager restrictions and gain access to files it would otherwise\nbe unable to access, or possibly terminate the Java Virtual Machine (JVM).\nThe HTTP NIO connector is used by default in JBoss Enterprise Web Server.\n(CVE-2011-2526)\n\nRed Hat would like to thank oCERT for reporting CVE-2011-4858, and the\nApache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges\nJulian W\u00e4lde and Alexander Klink as the original reporters of\nCVE-2011-4858.\n\nUsers of Tomcat should upgrade to these updated packages, which resolve\nthese issues. Tomcat must be restarted for this update to take effect.",

Summary
Red Hat Security Advisory: tomcat6 security and bug fix update
Notes
Topic
Updated tomcat6 packages that fix multiple security issues and three bugs
are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat
Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Apache Tomcat is a servlet container.
JBoss Enterprise Web Server includes the Tomcat Native library, providing
Apache Portable Runtime (APR) support for Tomcat. References in this text
to APR refer to the Tomcat Native implementation, not any other apr
package.
This update fixes the JBPAPP-4873, JBPAPP-6133, and JBPAPP-6852 bugs. It
also resolves the following security issues:
Multiple flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063,
CVE-2011-5064)
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw. (CVE-2011-3190)
A flaw in the way Tomcat recycled objects that contain data from user
requests (such as IP addresses and HTTP headers) when certain errors
occurred. If a user sent a request that caused an error to be logged,
Tomcat would return a reply to the next request (which could be sent by a
different user) with data from the first user's request, leading to
information disclosure. Under certain conditions, a remote attacker could
leverage this flaw to hijack sessions. (CVE-2011-3375)
The Java hashCode() method implementation was susceptible to predictable
hash collisions. A remote attacker could use this flaw to cause Tomcat to
use an excessive amount of CPU time by sending an HTTP request with a large
number of parameters whose names map to the same hash value. This update
introduces a limit on the number of parameters processed per request to
mitigate this issue. The default limit is 512 for parameters and 128 for
headers. These defaults can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2011-4858)
Tomcat did not handle large numbers of parameters and large parameter
values efficiently. A remote attacker could make Tomcat use an excessive
amount of CPU time by sending an HTTP request containing a large number of
parameters or large parameter values. This update introduces limits on the
number of parameters and headers processed per request to address this
issue. Refer to the CVE-2011-4858 description for information about the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
A flaw in the Tomcat MemoryUserDatabase. If a runtime exception occurred
when creating a new user with a JMX client, that user's password was logged
to Tomcat log files. Note: By default, only administrators have access to
such log files. (CVE-2011-2204)
A flaw in the way Tomcat handled sendfile request attributes when using the
HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web application
running on a Tomcat instance could use this flaw to bypass security manager
restrictions and gain access to files it would otherwise be unable to
access, or possibly terminate the Java Virtual Machine (JVM). The HTTP NIO
connector is used by default in JBoss Enterprise Web Server.
(CVE-2011-2526)
Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the
Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges
Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4858.

Summary
Red Hat Security Advisory: tomcat5 security and bug fix update
Notes
Topic
An update for the Apache Tomcat 5 component for JBoss Enterprise Web Server
1.0.2 that fixes multiple security issues and two bugs is now available
from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.
JBoss Enterprise Web Server includes the Tomcat Native library, providing
Apache Portable Runtime (APR) support for Tomcat. References in this text
to APR refer to the Tomcat Native implementation, not any other apr
package.
This update includes bug fixes as documented in JBPAPP-4873 and
JBPAPP-6133. It also resolves the following security issues:
Multiple flaws were found in the way Tomcat handled HTTP DIGEST
authentication. These flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063,
CVE-2011-5064)
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw. (CVE-2011-3190)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause Tomcat to use an excessive amount of CPU time by sending an HTTP
request with a large number of parameters whose names map to the same hash
value. This update introduces a limit on the number of parameters processed
per request to mitigate this issue. The default limit is 512 for parameters
and 128 for headers. These defaults can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2011-4858)
It was found that Tomcat did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make Tomcat use
an excessive amount of CPU time by sending an HTTP request containing a
large number of parameters or large parameter values. This update
introduces limits on the number of parameters and headers processed per
request to address this issue. Refer to the CVE-2011-4858 description for
information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception
occurred when creating a new user with a JMX client, that user's password
was logged to Tomcat log files. Note: By default, only administrators have
access to such log files. (CVE-2011-2204)
A flaw was found in the way Tomcat handled sendfile request attributes
when using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious
web application running on a Tomcat instance could use this flaw to bypass
security manager restrictions and gain access to files it would otherwise
be unable to access, or possibly terminate the Java Virtual Machine (JVM).
The HTTP NIO connector is used by default in JBoss Enterprise Web Server.
(CVE-2011-2526)
Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the
Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges
Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4858.
All users of JBoss Enterprise Web Server 1.0.2 as provided from the Red Hat
Customer Portal are advised to apply this update.

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
Updated jbossweb packages that fix multiple security issues are now
available for JBoss Enterprise Web Platform 5.1.2 for Red Hat Enterprise
Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Web is a web container based on Apache Tomcat. It provides a single
deployment platform for the JavaServer Pages (JSP) and Java Servlet
technologies.
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause JBoss Web to use an excessive amount of CPU time by sending an HTTP
request with a large number of parameters whose names map to the same hash
value. This update introduces a limit on the number of parameters and
headers processed per request to mitigate this issue. The default limit is
512 for parameters and 128 for headers. These defaults can be changed by
setting the "-Dorg.apache.tomcat.util.http.Parameters.MAX_COUNT=x" and
"-Dorg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT=x" system properties
as JAVA_OPTS entries in "jboss-as-web/bin/run.conf". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying this update, back up your JBoss Enterprise Web
Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory and any other
customized configuration files.
Users of JBoss Enterprise Web Platform 5.1.2 on Red Hat Enterprise Linux 4,
5, and 6 should upgrade to these updated packages, which correct these
issues. The JBoss server process must be restarted for this update to take
effect.

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
Updated jbossweb packages that fix multiple security issues are now
available for JBoss Enterprise Application Platform 5.1.2 for Red Hat
Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise
Application Platform. It provides a single deployment platform for the
JavaServer Pages (JSP) and Java Servlet technologies.
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was
susceptible to predictable hash collisions. A remote attacker could use
this flaw to cause JBoss Web to use an excessive amount of CPU time by
sending an HTTP request with a large number of parameters whose names map
to the same hash value. This update introduces a limit on the number of
parameters and headers processed per request to mitigate this issue. The
default limit is 512 for parameters and 128 for headers. These defaults
can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"jboss-as/server/[PROFILE]/deploy/properties-service.xml". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's "jboss-as/server/[PROFILE]/deploy/" directory, along
with all other customized configuration files.
Users of JBoss Enterprise Application Platform 5.1.2 on Red Hat Enterprise
Linux 4, 5, and 6 should upgrade to these updated packages, which correct
these issues. The JBoss server process must be restarted for this update to
take effect.

Summary
Red Hat Security Advisory: tomcat6 security and bug fix update
Notes
Topic
An update for the Apache Tomcat 6 component for JBoss Enterprise Web Server
1.0.2 that fixes multiple security issues and three bugs is now available
from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Apache Tomcat is a servlet container.
JBoss Enterprise Web Server includes the Tomcat Native library, providing
Apache Portable Runtime (APR) support for Tomcat. References in this text
to APR refer to the Tomcat Native implementation, not any other apr
package.
This update fixes the JBPAPP-4873, JBPAPP-6133, and JBPAPP-6852 bugs. It
also resolves the following security issues:
Multiple flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063,
CVE-2011-5064)
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw. (CVE-2011-3190)
A flaw in the way Tomcat recycled objects that contain data from user
requests (such as IP addresses and HTTP headers) when certain errors
occurred. If a user sent a request that caused an error to be logged,
Tomcat would return a reply to the next request (which could be sent by a
different user) with data from the first user's request, leading to
information disclosure. Under certain conditions, a remote attacker could
leverage this flaw to hijack sessions. (CVE-2011-3375)
The Java hashCode() method implementation was susceptible to predictable
hash collisions. A remote attacker could use this flaw to cause Tomcat to
use an excessive amount of CPU time by sending an HTTP request with a large
number of parameters whose names map to the same hash value. This update
introduces a limit on the number of parameters processed per request to
mitigate this issue. The default limit is 512 for parameters and 128 for
headers. These defaults can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2011-4858)
Tomcat did not handle large numbers of parameters and large parameter
values efficiently. A remote attacker could make Tomcat use an excessive
amount of CPU time by sending an HTTP request containing a large number of
parameters or large parameter values. This update introduces limits on the
number of parameters and headers processed per request to address this
issue. Refer to the CVE-2011-4858 description for information about the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
A flaw in the Tomcat MemoryUserDatabase. If a runtime exception occurred
when creating a new user with a JMX client, that user's password was logged
to Tomcat log files. Note: By default, only administrators have access to
such log files. (CVE-2011-2204)
A flaw in the way Tomcat handled sendfile request attributes when using the
HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web application
running on a Tomcat instance could use this flaw to bypass security manager
restrictions and gain access to files it would otherwise be unable to
access, or possibly terminate the Java Virtual Machine (JVM). The HTTP NIO
connector is used by default in JBoss Enterprise Web Server.
(CVE-2011-2526)
Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the
Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges
Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4858.

Summary
Red Hat Security Advisory: tomcat6 security and bug fix update
Notes
Topic
Updated tomcat6 packages that fix several security issues and one bug are
now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.
APR (Apache Portable Runtime) as mentioned in the CVE-2011-3190 and
CVE-2011-2526 descriptions does not refer to APR provided by the apr
packages. It refers to the implementation of APR provided by the Tomcat
Native library, which provides support for using APR with Tomcat. This
library is not shipped with Red Hat Enterprise Linux 6. This update
includes fixes for users who have elected to use APR with Tomcat by taking
the Tomcat Native library from a different product. Such a configuration is
not supported by Red Hat, however.
Multiple flaws were found in the way Tomcat handled HTTP DIGEST
authentication. These flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks. (CVE-2011-1184)
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw. (CVE-2011-3190)
A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception
occurred when creating a new user with a JMX client, that user's password
was logged to Tomcat log files. Note: By default, only administrators have
access to such log files. (CVE-2011-2204)
A flaw was found in the way Tomcat handled sendfile request attributes when
using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web
application running on a Tomcat instance could use this flaw to bypass
security manager restrictions and gain access to files it would otherwise
be unable to access, or possibly terminate the Java Virtual Machine (JVM).
The HTTP blocking IO (BIO) connector, which is not vulnerable to this
issue, is used by default in Red Hat Enterprise Linux 6. (CVE-2011-2526)
Red Hat would like to thank the Apache Tomcat project for reporting the
CVE-2011-2526 issue.
This update also fixes the following bug:
* Previously, in certain cases, if "LANG=fr_FR" or "LANG=fr_FR.UTF-8" was
set as an environment variable or in "/etc/sysconfig/tomcat6" on 64-bit
PowerPC systems, Tomcat may have failed to start correctly. With this
update, Tomcat works as expected when LANG is set to "fr_FR" or
"fr_FR.UTF-8". (BZ#748807)
Users of Tomcat should upgrade to these updated packages, which contain
backported patches to correct these issues. Tomcat must be restarted for
this update to take effect.

Summary
Red Hat Security Advisory: JBoss Enterprise Portal Platform 4.3 CP07 update
Notes
Topic
JBoss Enterprise Portal Platform 4.3 CP07, which fixes multiple security
issues and various bugs, is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Enterprise Portal Platform is the open source implementation of the
Java EE suite of services and Portal services running atop JBoss Enterprise
Application Platform. It comprises a set of offerings for enterprise
customers who are looking for pre-configured profiles of JBoss Enterprise
Middleware components that have been tested and certified together to
provide an integrated experience.
This JBoss Enterprise Portal Platform 4.3 CP07 release serves as a
replacement for JBoss Enterprise Portal Platform 4.3 CP06. Refer to the
JBoss Enterprise Portal Platform 4.3 CP07 Release Notes, available shortly
from docs.redhat.com, for information on the most significant bug fixes
included in this release.
The following security fixes are also included:
JBoss Seam 2 did not properly block access to JBoss Expression Language
(EL) constructs in page exception handling, allowing arbitrary Java methods
to be executed. A remote attacker could use this flaw to execute arbitrary
code via a specially-crafted URL provided to certain applications based on
the JBoss Seam 2 framework. Note: A properly configured and enabled Java
Security Manager would prevent exploitation of this flaw. (CVE-2011-1484)
Note: If you have created custom applications that are packaged with a copy
of the JBoss Seam 2 library, those applications must be rebuilt with the
updated jboss-seam.jar file provided by this update.
It was found that the Java hashCode() method implementation was
susceptible to predictable hash collisions. A remote attacker could use
this flaw to cause JBoss Web to use an excessive amount of CPU time by
sending an HTTP request with a large number of parameters whose names map
to the same hash value. This update introduces a limit on the number of
parameters and headers processed per request to mitigate this issue. The
default limit is 512 for parameters and 128 for headers. These defaults
can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"server/$PROFILE/deploy/properties-service.xml". (CVE-2011-4858)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
The invoker servlets, deployed by default via httpha-invoker, only
performed access control on the HTTP GET and POST methods, allowing remote
attackers to make unauthenticated requests by using different HTTP methods.
Due to the second layer of authentication provided by a security
interceptor, this issue is not exploitable on default installations unless
an administrator has misconfigured the security interceptor or disabled it.
(CVE-2011-4085)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank Martin Kouba from IT SYSTEMS a.s. for reporting
CVE-2011-1484; oCERT for reporting CVE-2011-4858; and the Apache Tomcat
project for reporting CVE-2011-2526. oCERT acknowledges Julian Wälde and
Alexander Klink as the original reporters of CVE-2011-4858.
Warning: Before applying this update, back up all applications deployed on
JBoss Enterprise Portal Platform, along with all customized configuration
files.
All users of JBoss Enterprise Portal Platform 4.3 CP06 as provided from the
Red Hat Customer Portal are advised to upgrade to JBoss Enterprise Portal
Platform 4.3 CP07.

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
An update for JBoss Enterprise BRMS Platform 5.2.0, JBoss Enterprise Portal
Platform 5.2.0, and JBoss Enterprise SOA Platform 5.2.0 that fixes multiple
security issues is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Web is a web container based on Apache Tomcat. It provides a single
deployment platform for the JavaServer Pages (JSP) and Java Servlet
technologies.
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause JBoss Web to use an excessive amount of CPU time by sending an HTTP
request with a large number of parameters whose names map to the same hash
value. This update introduces a limit on the number of parameters and
headers processed per request to mitigate this issue. The default limit is
512 for parameters and 128 for headers. These defaults can be changed by
setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"jboss-as/server/[PROFILE]/deploy/properties-service.xml". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying this update, back up your JBoss installation,
including any databases, applications, configuration files, and so on.
All users of JBoss Enterprise BRMS Platform 5.2.0, JBoss Enterprise Portal
Platform 5.2.0, and JBoss Enterprise SOA Platform 5.2.0 as provided from
the Red Hat Customer Portal are advised to install this update.

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
An update for JBoss Enterprise Application Platform 4.3.0 CP10 that fixes
multiple security issues is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
JBoss Web Server is the web container, based on Apache Tomcat, in JBoss
Enterprise Application Platform. It provides a single deployment platform
for the JavaServer Pages (JSP) and Java Servlet technologies.
Multiple flaws were found in the way JBoss Web Server handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web Server HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause JBoss Web Server to use an excessive amount of CPU time by sending an
HTTP request with a large number of parameters whose names map to the same
hash value. This update introduces a limit on the number of parameters and
headers processed per request to mitigate this issue. The default limit is
512 for parameters and 128 for headers. These defaults can be changed by
setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"jboss-as/server/[PROFILE]/deploy/properties-service.xml". (CVE-2011-4858)
A flaw was found in the way JBoss Web Server handled sendfile request
attributes when using the HTTP APR (Apache Portable Runtime) or NIO
(Non-Blocking I/O) connector. A malicious web application running on a
JBoss Web Server instance could use this flaw to bypass security manager
restrictions and gain access to files it would otherwise be unable to
access, or possibly terminate the Java Virtual Machine (JVM).
(CVE-2011-2526)
Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the
Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges
Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4858.
Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's "jboss-as/server/[PROFILE]/deploy/" directory, along
with all other customized configuration files.
All users of JBoss Enterprise Application Platform 4.3.0 CP10 as provided
from the Red Hat Customer Portal are advised to install this update.

"text": "JBoss Web Server is the web container, based on Apache Tomcat, in JBoss\nEnterprise Application Platform. It provides a single deployment platform\nfor the JavaServer Pages (JSP) and Java Servlet technologies.\n\nMultiple flaws were found in the way JBoss Web Server handled HTTP DIGEST\nauthentication. These flaws weakened the JBoss Web Server HTTP DIGEST\nauthentication implementation, subjecting it to some of the weaknesses of\nHTTP BASIC authentication, for example, allowing remote attackers to\nperform session replay attacks. (CVE-2011-1184, CVE-2011-5062,\nCVE-2011-5063, CVE-2011-5064)\n\nIt was found that the Java hashCode() method implementation was susceptible\nto predictable hash collisions. A remote attacker could use this flaw to\ncause JBoss Web Server to use an excessive amount of CPU time by sending an\nHTTP request with a large number of parameters whose names map to the same\nhash value. This update introduces a limit on the number of parameters and\nheaders processed per request to mitigate this issue. The default limit is\n512 for parameters and 128 for headers. These defaults can be changed by\nsetting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and\norg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in\n\"jboss-as/server/[PROFILE]/deploy/properties-service.xml\". (CVE-2011-4858)\n\nA flaw was found in the way JBoss Web Server handled sendfile request\nattributes when using the HTTP APR (Apache Portable Runtime) or NIO\n(Non-Blocking I/O) connector. A malicious web application running on a\nJBoss Web Server instance could use this flaw to bypass security manager\nrestrictions and gain access to files it would otherwise be unable to\naccess, or possibly terminate the Java Virtual Machine (JVM).\n(CVE-2011-2526)\n\nRed Hat would like to thank oCERT for reporting CVE-2011-4858, and the\nApache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges\nJulian W\u00e4lde and Alexander Klink as the original reporters of\nCVE-2011-4858.\n\nWarning: Before applying this update, back up your JBoss Enterprise\nApplication Platform\u0027s \"jboss-as/server/[PROFILE]/deploy/\" directory, along\nwith all other customized configuration files.\n\nAll users of JBoss Enterprise Application Platform 4.3.0 CP10 as provided\nfrom the Red Hat Customer Portal are advised to install this update.",

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
An update for JBoss Enterprise Web Platform 5.1.2 that fixes multiple
security issues is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Web is a web container based on Apache Tomcat. It provides a single
deployment platform for the JavaServer Pages (JSP) and Java Servlet
technologies.
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was susceptible
to predictable hash collisions. A remote attacker could use this flaw to
cause JBoss Web to use an excessive amount of CPU time by sending an HTTP
request with a large number of parameters whose names map to the same hash
value. This update introduces a limit on the number of parameters and
headers processed per request to mitigate this issue. The default limit is
512 for parameters and 128 for headers. These defaults can be changed by
setting the "-Dorg.apache.tomcat.util.http.Parameters.MAX_COUNT=x" and
"-Dorg.apache.tomcat.util.http.MimeHeaders.MAX_COUNT=x" system properties
as JAVA_OPTS entries in "jboss-as-web/bin/run.conf". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying this update, back up your JBoss Enterprise Web
Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory and any other
customized configuration files.
All users of JBoss Enterprise Web Platform 5.1.2 as provided from the Red
Hat Customer Portal are advised to install this update.

Summary
Red Hat Security Advisory: jbossweb security update
Notes
Topic
An update for JBoss Enterprise Application Platform 5.1.2 that fixes
multiple security issues is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise
Application Platform. It provides a single deployment platform for the
JavaServer Pages (JSP) and Java Servlet technologies.
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was
susceptible to predictable hash collisions. A remote attacker could use
this flaw to cause JBoss Web to use an excessive amount of CPU time by
sending an HTTP request with a large number of parameters whose names map
to the same hash value. This update introduces a limit on the number of
parameters and headers processed per request to mitigate this issue. The
default limit is 512 for parameters and 128 for headers. These defaults
can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"jboss-as/server/[PROFILE]/deploy/properties-service.xml". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request attributes
when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O)
connector. A malicious web application running on a JBoss Web instance
could use this flaw to bypass security manager restrictions and gain access
to files it would otherwise be unable to access, or possibly terminate the
Java Virtual Machine (JVM). (CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's "jboss-as/server/[PROFILE]/deploy/" directory, along
with all other customized configuration files.
All users of JBoss Enterprise Application Platform 5.1.2 as provided from
the Red Hat Customer Portal are advised to install this update.

Summary
Red Hat Security Advisory: JBoss Communications Platform 5.1.3 update
Notes
Topic
JBoss Communications Platform 5.1.3, which fixes multiple security issues
and various bugs, is now available from the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
Details
The JBoss Communications Platform (JBCP) is an open source VoIP platform
certified for JAIN SLEE 1.1 and SIP Servlets 1.1 compliance. JBCP serves as
a high performance core for Service Delivery Platforms (SDPs) and IP
Multimedia Subsystems (IMSs) by leveraging J2EE to enable the convergence
of data and video in Next-Generation Intelligent Network (NGIN)
applications.
This JBoss Communications Platform 5.1.3 release serves as a replacement
for JBoss Communications Platform 5.1.2, and includes various bug fixes.
Refer to the JBoss Communications Platform 5.1.3 Release Notes for
information on the most significant of these changes. The Release Notes
will be available shortly from
https://docs.redhat.com/docs/en-US/index.html
The following security issues are also fixed with this release:
A flaw was found in the way JBoss Web handled UTF-8 surrogate pair
characters. If JBoss Web was hosting an application with UTF-8 character
encoding enabled, or that included user-supplied UTF-8 strings in a
response, a remote attacker could use this flaw to cause a denial of
service (infinite loop) on the JBoss Web server. (CVE-2011-4610)
It was found that the Java hashCode() method implementation was
susceptible to predictable hash collisions. A remote attacker could use
this flaw to cause JBoss Web to use an excessive amount of CPU time by
sending an HTTP request with a large number of parameters whose names map
to the same hash value. This update introduces a limit on the number of
parameters and headers processed per request to mitigate this issue. The
default limit is 512 for parameters and 128 for headers. These defaults
can be changed by setting the
org.apache.tomcat.util.http.Parameters.MAX_COUNT and
org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties in
"server/$PROFILE/deploy/properties-service.xml". (CVE-2011-4858)
It was found that JBoss Web did not handle large numbers of parameters and
large parameter values efficiently. A remote attacker could make a JBoss
Web server use an excessive amount of CPU time by sending an HTTP request
containing a large number of parameters or large parameter values. This
update introduces limits on the number of parameters and headers processed
per request to address this issue. Refer to the CVE-2011-4858 description
for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT
and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties.
(CVE-2012-0022)
Multiple flaws were found in the way JBoss Web handled HTTP DIGEST
authentication. These flaws weakened the JBoss Web HTTP DIGEST
authentication implementation, subjecting it to some of the weaknesses of
HTTP BASIC authentication, for example, allowing remote attackers to
perform session replay attacks. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
A flaw was found in the way JBoss Web handled sendfile request
attributes when using the HTTP APR (Apache Portable Runtime) or NIO
(Non-Blocking I/O) connector. A malicious web application running on a
JBoss Web instance could use this flaw to bypass security manager
restrictions and gain access to files it would otherwise be unable to
access, or possibly terminate the Java Virtual Machine (JVM).
(CVE-2011-2526)
Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; oCERT for
reporting CVE-2011-4858; and the Apache Tomcat project for reporting
CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the
original reporters of CVE-2011-4858.
Warning: Before applying the update, back up your existing JBoss
Communications Platform installation (including its databases,
applications, configuration files, and so on).
All users of JBoss Communications Platform 5.1.2 as provided from the Red
Hat Customer Portal are advised to upgrade to JBoss Communications Platform
5.1.3.
