Red Hat Security Advisory

 

Synopsis: Low: httpd security, bug fix, and enhancement update

Advisory ID: RHSA-2013:0512-02

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0512.html

Issue date: 2013-02-21

CVE Names: CVE-2008-0455 CVE-2012-2687 CVE-2012-4557

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64

Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64

 

3. 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.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.
