===================================================================== Red Hat Security Advisory
Synopsis: Moderate: httpd security update Advisory ID: RHSA-2014:0369-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0369.html Issue date: 2014-04-03 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 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
