Summary
Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.

Summary
Red Hat Security Advisory: glibc security update
Notes
Topic
Updated glibc packages are available which fix a buffer overflow in the XDR
decoder and two vulnerabilities in the resolver functions.
[updated 8 aug 2002]
Updated packages have been made available, as the original errata introduced
a bug which could cause calloc() to crash on 32-bit platforms when passed a
size of 0. These updated errata packages contain a patch to correct this bug.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system. Sun RPC is a remote procedure call
framework which allows clients to invoke procedures in a server process
over a network. XDR is a mechanism for encoding data structures for use
with RPC. NFS, NIS, and other network services that are built upon Sun
RPC. The glibc package contains an XDR encoder/decoder derived from Sun's
RPC implementation which was recently demonstrated to be vulnerable to a
heap overflow.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder can result in a heap buffer overflow in glibc 2.2.5 and
earlier. Depending upon the application, this vulnerability may be
exploitable and could lead to arbitrary code execution. (CAN-2002-0391)
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in the /etc/nsswitch.conf file includes the "dns"
entry. By default, Red Hat Linux Advanced Server ships with "networks"
set to "files" and is therefore not vulnerable to this issue.
(CAN-2002-0684)
A related issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
All users should upgrade to these errata packages which contain patches to
the glibc libraries and therefore are not vulnerable to these issues.
Thanks to Solar Designer for providing patches for this issue.

Summary
Red Hat Security Advisory: glibc security update
Notes
Topic
Updated glibc packages are available which fix a buffer overflow in the XDR
decoder and two vulnerabilities in the resolver functions.
[updated 8 aug 2002]
Updated packages have been made available, as the original errata introduced
a bug which could cause calloc() to crash on 32-bit platforms when passed a
size of 0. These updated errata packages contain a patch to correct this bug.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system. Sun RPC is a remote procedure call
framework which allows clients to invoke procedures in a server process
over a network. XDR is a mechanism for encoding data structures for use
with RPC. NFS, NIS, and other network services that are built upon Sun
RPC. The glibc package contains an XDR encoder/decoder derived from Sun's
RPC implementation which was recently demonstrated to be vulnerable to a
heap overflow.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder can result in a heap buffer overflow in glibc 2.2.5 and
earlier. Depending upon the application, this vulnerability may be
exploitable and could lead to arbitrary code execution. (CAN-2002-0391)
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in the /etc/nsswitch.conf file includes the "dns"
entry. By default, Red Hat Linux Advanced Server ships with "networks"
set to "files" and is therefore not vulnerable to this issue.
(CAN-2002-0684)
A related issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
All users should upgrade to these errata packages which contain patches to
the glibc libraries and therefore are not vulnerable to these issues.

Summary
Red Hat Security Advisory: : Updated glibc packages fix vulnerabilities in resolver
Notes
Topic
Updated glibc packages are available to fix two vulnerabilities in the
resolver functions.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in /etc/nsswitch.conf includes the "dns" entry. By
default, Red Hat Linux ships with "networks" set to "files" and
is therefore not vulnerable to this issue. (CAN-2002-0684)
A second, related, issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
These errata packages for Red Hat Linux 7.1 and 7.2 on the Itanium
architecture also include a fix for the strncpy implementation in some
boundary cases.
All users should upgrade to these errata packages which contain patches to
the glibc and glibc-compat libraries and therefore are not vulnerable to

Summary
Red Hat Security Advisory: : : : Updated glibc packages fix vulnerabilities
Notes
Topic
Updated glibc packages that fix a number of vulnerabilites are now available.
Details
The glibc package contains standard libraries that are used by
multiple programs.
An integer overflow is present in the xdrmem_getbytes() function of glibc
2.3.1 and earlier. Depending upon the application, this vulnerability
could cause buffer overflows and may be exploitable, leading to arbitrary
code execution.
Red Hat would like to thank eEye Digital Security for alerting us to this
issue.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder in glibc 2.2.5 and earlier can result in a heap buffer
overflow. Depending upon the application, this vulnerability may be
exploitable and lead to arbitrary code execution.
A read buffer overflow vulnerability exists in the glibc resolver code in
versions of glibc up to and including 2.2.5. The vulnerability is triggered
by DNS packets larger than 1024 bytes and can cause applications to crash.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the "networks"
database in /etc/nsswitch.conf includes the "dns" entry. By default, Red
Hat Linux ships with "networks" set to "files" and is therefore not
vulnerable to this issue. (CAN-2002-0684)
All users should upgrade to these errata packages, which contain patches to
the glibc libraries and are therefore not vulnerable to these issues.
NOTE: Once the glibc upgrade has been completed, you must either reboot the
system or restart all programs on the system (for example, by using telinit
1 and then switching back to the original runlevel). Rebooting the system
or restarting the system programs is necessary to avoid vulnerable glibc
copies in memory. In addition, one cannot mix old NSS modules or libresolv
with upgraded NSS modules or libresolve in one running application.
Note also that, if sshd is running so that the other services can be
restarted remotely or for a remote reboot during an unattended glibc
upgrade, glibc will also restart sshd.

Summary
Red Hat Security Advisory: : Updated glibc packages fix vulnerabilities in resolver
Notes
Topic
Updated glibc packages are available to fix two vulnerabilities in the
resolver functions.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in /etc/nsswitch.conf includes the "dns" entry. By
default, Red Hat Linux ships with "networks" set to "files" and
is therefore not vulnerable to this issue. (CAN-2002-0684)
A second, related, issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
These errata packages for Red Hat Linux 7.1 and 7.2 on the Itanium
architecture also include a fix for the strncpy implementation in some
boundary cases.
All users should upgrade to these errata packages which contain patches to
the glibc and glibc-compat libraries and therefore are not vulnerable to
these issues.

Summary
Red Hat Security Advisory: glibc security update
Notes
Topic
Updated glibc packages are available which fix a buffer overflow in the XDR
decoder and two vulnerabilities in the resolver functions.
[updated 8 aug 2002]
Updated packages have been made available, as the original errata introduced
a bug which could cause calloc() to crash on 32-bit platforms when passed a
size of 0. These updated errata packages contain a patch to correct this bug.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system. Sun RPC is a remote procedure call
framework which allows clients to invoke procedures in a server process
over a network. XDR is a mechanism for encoding data structures for use
with RPC. NFS, NIS, and other network services that are built upon Sun
RPC. The glibc package contains an XDR encoder/decoder derived from Sun's
RPC implementation which was recently demonstrated to be vulnerable to a
heap overflow.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder can result in a heap buffer overflow in glibc 2.2.5 and
earlier. Depending upon the application, this vulnerability may be
exploitable and could lead to arbitrary code execution. (CAN-2002-0391)
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in the /etc/nsswitch.conf file includes the "dns"
entry. By default, Red Hat Linux Advanced Server ships with "networks"
set to "files" and is therefore not vulnerable to this issue.
(CAN-2002-0684)
A related issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
All users should upgrade to these errata packages which contain patches to
the glibc libraries and therefore are not vulnerable to these issues.

Summary
Red Hat Security Advisory: : Updated glibc packages fix vulnerabilities in resolver
Notes
Topic
Updated glibc packages are available to fix two vulnerabilities in the
resolver functions.
Details
The glibc package contains standard libraries which are used by
multiple programs on the system.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the
"networks" database in /etc/nsswitch.conf includes the "dns" entry. By
default, Red Hat Linux ships with "networks" set to "files" and
is therefore not vulnerable to this issue. (CAN-2002-0684)
A second, related, issue is a bug in the glibc-compat packages, which
provide compatibility for applications compiled against glibc version
2.0.x. Applications compiled against this version (such as those
distributed with early Red Hat Linux releases 5.0, 5.1, and 5.2) could also
be vulnerable to this issue. (CAN-2002-0651)
These errata packages for Red Hat Linux 7.1 and 7.2 on the Itanium
architecture also include a fix for the strncpy implementation in some
boundary cases.
All users should upgrade to these errata packages which contain patches to
the glibc and glibc-compat libraries and therefore are not vulnerable to
these issues.

Summary
Red Hat Security Advisory: : : : Updated glibc packages fix vulnerabilities
Notes
Topic
Updated glibc packages that fix a number of vulnerabilites are now available.
Details
The glibc package contains standard libraries that are used by
multiple programs.
An integer overflow is present in the xdrmem_getbytes() function of glibc
2.3.1 and earlier. Depending upon the application, this vulnerability
could cause buffer overflows and may be exploitable, leading to arbitrary
code execution.
Red Hat would like to thank eEye Digital Security for alerting us to this
issue.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder in glibc 2.2.5 and earlier can result in a heap buffer
overflow. Depending upon the application, this vulnerability may be
exploitable and lead to arbitrary code execution.
A read buffer overflow vulnerability exists in the glibc resolver code in
versions of glibc up to and including 2.2.5. The vulnerability is triggered
by DNS packets larger than 1024 bytes and can cause applications to crash.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the "networks"
database in /etc/nsswitch.conf includes the "dns" entry. By default, Red
Hat Linux ships with "networks" set to "files" and is therefore not
vulnerable to this issue. (CAN-2002-0684)
All users should upgrade to these errata packages, which contain patches to
the glibc libraries and are therefore not vulnerable to these issues.
NOTE: Once the glibc upgrade has been completed, you must either reboot the
system or restart all programs on the system (for example, by using telinit
1 and then switching back to the original runlevel). Rebooting the system
or restarting the system programs is necessary to avoid vulnerable glibc
copies in memory. In addition, one cannot mix old NSS modules or libresolv
with upgraded NSS modules or libresolve in one running application.
Note also that, if sshd is running so that the other services can be
restarted remotely or for a remote reboot during an unattended glibc
upgrade, glibc will also restart sshd.

Summary
Red Hat Security Advisory: : : : Updated glibc packages fix vulnerabilities
Notes
Topic
Updated glibc packages that fix a number of vulnerabilites are now available.
Details
The glibc package contains standard libraries that are used by
multiple programs.
An integer overflow is present in the xdrmem_getbytes() function of glibc
2.3.1 and earlier. Depending upon the application, this vulnerability
could cause buffer overflows and may be exploitable, leading to arbitrary
code execution.
Red Hat would like to thank eEye Digital Security for alerting us to this
issue.
An error in the calculation of memory needed for unpacking arrays in the
XDR decoder in glibc 2.2.5 and earlier can result in a heap buffer
overflow. Depending upon the application, this vulnerability may be
exploitable and lead to arbitrary code execution.
A read buffer overflow vulnerability exists in the glibc resolver code in
versions of glibc up to and including 2.2.5. The vulnerability is triggered
by DNS packets larger than 1024 bytes and can cause applications to crash.
A buffer overflow vulnerability has been found in the way the glibc
resolver handles the resolution of network names and addresses via DNS (as
per Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are
affected. A system would be vulnerable to this issue if the "networks"
database in /etc/nsswitch.conf includes the "dns" entry. By default, Red
Hat Linux ships with "networks" set to "files" and is therefore not
vulnerable to this issue. (CAN-2002-0684)
All users should upgrade to these errata packages, which contain patches to
the glibc libraries and are therefore not vulnerable to these issues.
NOTE: Once the glibc upgrade has been completed, you must either reboot the
system or restart all programs on the system (for example, by using telinit
1 and then switching back to the original runlevel). Rebooting the system
or restarting the system programs is necessary to avoid vulnerable glibc
copies in memory. In addition, one cannot mix old NSS modules or libresolv
with upgraded NSS modules or libresolve in one running application.
Note also that, if sshd is running so that the other services can be
restarted remotely or for a remote reboot during an unattended glibc
upgrade, glibc will also restart sshd.
