The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk
Multi-Processing Module (apache-mpm-itk) 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 (CVE-2011-1176).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:

The updated packages uses the latest upstream ITK patch for apache
that is unaffected by this issue.
