(RHSA-2006:0161) RHAPS security and enhancement update

Red Hat Application Server packages provide a J2EE Application Server and
Web container as well as the underlying Java stack.

A denial of service flaw was found in the way Apache Tomcat displays
directory listings. A remote attacker could cause Tomcat to consume large
amounts of CPU resources by sending multiple requests for a directory
containing a large number of files. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-3510 to this issue.
This update contains a version of Apache Tomcat that will recover after
the aforementioned attack. Users are also advised to disable directory
listing for web directories that contain very large numbers of files.

A cross-site scripting flaw was found in the way Struts displays error
pages. It may be possible for an attacker to construct a specially crafted
URL which could fool a victim into believing they are viewing a trusted
site. The Common Vulnerabilities and Exposures project has assigned the
name CVE-2005-3745 to this issue. Please note that this issue does not
affect Struts running on Tomcat or JOnAS, which is our supported usage of
Struts.

Additionally, this update replaces some other outdated packages with new
versions. Several bug fixes and enhancements are included in these new
versions.

IMPORTANT: Before applying this update, read the detailed
installation/upgrade instructions in the RELEASE_NOTES document.

All users of Red Hat Application Server should upgrade to these updated
packages, which contain packages that are not vulnerable to these issues.
