NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd package and not the httpd package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow.
