Summary
Red Hat Security Advisory: httpd security and bug fix update

Notes

Topic
An update for the Apache HTTP Server component for JBoss Enterprise Web Server 1.0.2 that fixes multiple security issues and one bug 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
The Apache HTTP Server ("httpd") is the namesake project of The Apache Software Foundation. It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker. (CVE-2011-3368) It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period or until all back-end servers were marked as failed. (CVE-2011-3348) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a ".htaccess" file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the "apache" user. (CVE-2011-3607) A NULL pointer dereference flaw was found in the httpd mod_log_config module. In configurations where cookie logging is enabled, a remote attacker could use this flaw to crash the httpd child process via an HTTP request with a malformed Cookie header. (CVE-2012-0021) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) Red Hat would like to thank Context Information Security for reporting the CVE-2011-3368 issue. This update also fixes the following bug: * The fix for CVE-2011-3192 provided by the RHSA-2011:1330 update introduced a regression in the way httpd handled certain Range HTTP header values. This update corrects this regression. (BZ#749071) All users of JBoss Enterprise Web Server 1.0.2 as provided from the Red Hat Customer Portal are advised to apply this update.
