Summary

The Apache HTTP Server is a popular web server.
A flaw was found in the way the mod_dav module of the Apache HTTP Server handled merge requests. An attacker could use this flaw to send a crafted merge request that contains URIs that are not configured for DAV, causing the httpd child process to crash. (CVE-2013-1896)
All httpd users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the httpd daemon will be restarted automatically.
