Description

From Red Hat Security Advisory 2007:0395 :

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.

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.
