Security Advisory Important: mod_jk security update

Advisory: RHSA-2007:0380-2
Type: Security Advisory
Severity: Important
Issued on: 2007-05-30
Last updated on: 2007-05-30
Affected Products: Application Server v2 EL4
CVEs ( CVE-2007-1860


Updated mod_jk packages that fix a security issue are now available for Red
Hat Application Server.

This update has been rated as having Important security impact by the Red
Hat Security Response Team.

mod_jk is a Tomcat connector that can be used to communicate between Tomcat
and the Apache HTTP Server 2.

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.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
