RHSA-2007:0396 - Security Advisory

Topic

Updated mod_perl packages that fix a security issue are now available for Red
Hat Application Stack.

This update has been rated as having low 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 web server can directly execute Perl code.

An issue was found in the "namespace_from_uri" method of the
ModPerl::RegistryCooker class. If a server implemented a mod_perl registry
module using this method, a remote attacker requesting a carefully crafted
URI can cause 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
