Mandriva Linux Security Advisory MDVSA-2012:118

_______________________________________________________________________
Package : apache-mod_security
Date : July 27, 2012
Affected: Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
A vulnerability 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).
The updated packages have been patched to correct this issue.
