How to fix?

Upgrade apache/httpd to version 2.2.22 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). 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.
