3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

983549 - CVE-2013-1896 httpd: mod_dav DoS (httpd child process crash) via a URI MERGE request with source URI not handled by mod_dav
