Summary
Red Hat Security Advisory: mod_jk security update

Notes

Topic
Updated mod_jk packages that fix a security issue are now available for Red Hat Application Stack v1.1. This update has been rated as having Important security impact by the Red Hat Security Response Team.
Details
mod_jk is a Tomcat connector that can be used to communicate between Tomcat and the Apache HTTP Server 2. mod_jk was first distributed with Red Hat Application Stack version 1.1 released on 19 February 2007. Versions of mod_jk before 1.2.23 decoded request URLs by default inside Apache httpd and forwarded the encoded URL to Tomcat, which itself did a second decoding. If Tomcat was used behind mod_jk and configured to only proxy some contexts, an attacker could construct a carefully crafted HTTP request to work around the context restriction and potentially access non-proxied content (CVE-2007-1860). Users of mod_jk should upgrade to these updated packages, which address this issue by changing the default so mod_jk forwards the original unchanged request URL to Tomcat.

Only those\nRPMs which are currently installed will be updated. Those RPMs which are\nnot installed but included in the list will not be updated. Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains\nthe desired RPMs.\n\nPlease note that this update is also available via Red Hat Network. Many\npeople find this an easier way to apply updates. To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
