RHSA-2009:0446 - Security Advisory
Important: mod_jk security update
Security Advisory: Important
An updated mod_jk package that fixes a security issue is now available for
Red Hat Application Stack v2.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
mod_jk is an Apache Tomcat connector that allows Apache Tomcat and the
Apache HTTP Server to communicate with each other.
An information disclosure flaw was found in mod_jk. In certain situations,
if a faulty client set the "Content-Length" header without providing data,
or if a user sent repeated requests very quickly, one user may view a
response intended for another user. (CVE-2008-5519)
As well, the sample configuration files provided in the documentation have
been updated to reflect recommended practice.
All mod_jk users are advised to upgrade to this updated package. It
provides mod_jk 1.2.28, which is not vulnerable to this issue.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
