Subject: Security ERRATA Moderate: libxml2 on SL5.x, SL6.x i386/x86_64
MIME-Version: 1.0

Synopsis: Moderate: libxml2 security update
Issue Date: 2013-02-28
CVE Numbers: CVE-2013-0338
--

A denial of service flaw was found in the way libxml2 performed string
substitutions when entity values for entity references replacement was
enabled. A remote attacker could provide a specially-crafted XML file that,
when processed by an application linked against libxml2, would lead to
excessive CPU consumption. (CVE-2013-0338)

The desktop must be restarted (log out, then log back in) for this update to
take effect.
