Synopsis:          Moderate: httpd security update
Advisory ID:       RHSA-2014:0369-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2014:0369.html

CVE Names:         CVE-2013-6438 CVE-2014-0098 
====================================================================
1. Summary:

Updated httpd packages that fix two security issues are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate
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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The httpd packages provide the Apache HTTP Server, a powerful, efficient,
and extensible web server.

It was found that the mod_dav module did not correctly strip leading white
space from certain elements in a parsed XML. In certain httpd
configurations that use the mod_dav module (for example when using the
mod_dav_svn module), a remote attacker could send a specially crafted DAV
request that would cause the httpd child process to crash or, possibly,
allow the attacker to execute arbitrary code with the privileges of the
"apache" user. (CVE-2013-6438)

A buffer over-read flaw was found in the httpd mod_log_config module.
In configurations where cookie logging is enabled (on Red Hat Enterprise
Linux it is disabled by default), a remote attacker could use this flaw to
crash the httpd child process via an HTTP request with a malformed cookie
header. (CVE-2014-0098)

All httpd users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. 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
