Synopsis

Low: mod_perl security update

Type/Severity

Security Advisory: Low

Topic

Updated mod_perl packages that fix a security issue are now available for Red
Hat Enterprise Linux 3, 4, 5.

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
