RHSA-2013:0512 - Low: httpd security, bug fix, and enhancement update

Synopsis

Low: httpd security, bug fix, and enhancement update

Type/Severity

Security Advisory Low

Topic

Updated httpd packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

The httpd packages contain the Apache HTTP Server (httpd), which is the namesake project of The Apache Software Foundation.

An input sanitization flaw was found in the mod_negotiation Apache HTTP Server module. A remote attacker able to upload or create files with arbitrary names in a directory that has the MultiViews options enabled, could use this flaw to conduct cross-site scripting attacks against users visiting the site. (CVE-2008-0455, CVE-2012-2687)

It was discovered that mod_proxy_ajp, when used in configurations with mod_proxy in load balancer mode, would mark a back-end server as failed when request processing timed out, even when a previous AJP (Apache JServ Protocol) CPing request was responded to by the back-end. A remote attacker able to make a back-end use an excessive amount of time to process a request could cause mod_proxy to not send requests to back-end AJP servers for the retry timeout period or until all back-end servers were marked as failed. (CVE-2012-4557)

These updated httpd packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked to in the References, for information on the most significant of these changes.

All users of httpd are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. After installing the updated packages, the httpd daemon will be restarted automatically.
