Description

The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk Multi-Processing Module 2.2.11-01 and 2.2.11-02 for the Apache HTTP Server does not properly handle certain configuration sections that specify NiceValue but not AssignUserID, which might allow remote attackers to gain privileges by leveraging the root uid and root gid of an mpm-itk process.

Affected products

Debian Linux: 5.0, 6.0, 7.0
Mpm-Itk Project Mpm-Itk: 2.2.11-01, 2.2.11-02
