RHSA-2014:0826 - Security Advisory

Topic

Updated httpd packages that fix two security issues are now available for
Red Hat JBoss Enterprise Application Platform 6.2 for Red Hat Enterprise
Linux 5 and 6.

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.

Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

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, 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 users of Red Hat JBoss Enterprise Application Platform 6.2 should
upgrade to these updated packages, which contain backported patches to
correct these issues. After installing the updated packages, users must
restart the httpd service for the update to take effect.
