Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0826-01 - 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, 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.

3. 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.

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
https://access.redhat.com/site/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1077867 - CVE-2013-6438 httpd: mod_dav denial of service via crafted DAV WRITE request
1077871 - CVE-2014-0098 httpd: mod_log_config does not properly handle logging certain cookies resulting in DoS
