(RHSA-2009:1087) Important: mod_jk security update

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)

All mod_jk users are advised to upgrade to these updated packages. They
provide mod_jk 1.2.28, which is not vulnerable to this issue.
