RHSA-2007:0486 - Security Advisory

Topic

Updated mod_perl packages that fix a security issue are now available for Red
Hat Enterprise Linux 2.1.

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

Description

Mod_perl incorporates a Perl interpreter into the Apache web server,
so that the Apache HTTP server can directly execute Perl code.

The Apache::PerlRun module was found to not properly escape PATH_INFO
before being used in a regular expression. If a server is configured to
use Apache::PerlRun, an attacker could request a carefully crafted URI
causing resource consumption, which could lead to a denial of service
(CVE-2007-1349).

Users of mod_perl should update to these erratum packages which contain a
backported fix to correct this issue.

Solution

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

This update is available via Red Hat Network. Details on how to use
