Product:           Red Hat Application Stack
CVE Names:         CVE-2007-1349 
- ---------------------------------------------------------------------1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64
Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64

3. Problem 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.

4. 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 
the Red Hat Network to apply this update are available at
