Synopsis
========
The mod_perl Apache module is vulnerable to a Denial of Service when
processing regular expressions.
Background
==========
Mod_perl is an Apache module that embeds the Perl interpreter within
the server, allowing Perl-based web-applications to be created.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apache/mod_perl < 1.30 >= 1.30
>= 2.0.3-r1
www-apache/mod_perl < 2.0.3-r1 >= 1.30
>= 2.0.3-r1
Description
===========
Alex Solvey discovered that the "path_info" variable used in file
RegistryCooker.pm (mod_perl 2.x) or file PerlRun.pm (mod_perl 1.x), is
not properly escaped before being processed.
Impact
======
A remote attacker could send a specially crafted URL to the vulnerable
server, possibly resulting in a massive resource consumption.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All mod_perl 1.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_perl-1.30"
All mod_perl 2.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_perl-2.0.3-r1"
