Updated httpd packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
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.
