Package : apache-mod_security
Date : December 23, 2012
Affected: 2011.

Problem Description:

Multiple vulnerabilities has been discovered and corrected in
apache-mod_security:

ModSecurity before 2.6.6, when used with PHP, does not properly handle
single quotes not at the beginning of a request parameter value in
the Content-Disposition field of a request with a multipart/form-data
Content-Type header, which allows remote attackers to bypass filtering
rules and perform other attacks such as cross-site scripting (XSS)
attacks. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2009-5031 (CVE-2012-2751).

ModSecurity <= 2.6.8 is vulnerable to multipart/invalid part
ruleset bypass, this was fixed in 2.7.0 (released on2012-10-16)
(CVE-2012-4528).

The updated packages have been patched to correct these issues.
