CVE-2013-0339

First published: Mon Feb 25 2013(Updated: )

A denial of service flaw was found in the way libxml2, a library providing support to read, modify and write XML and HTML files, performed string substitutions when entity values for external entity references replacement (--noent option) was requested / enabled during the XML file parsing. A remote attacker could provide a specially-crafted XML file containing an external entity expansion, when processed would lead to excessive CPU consumption (denial of service). This a different flaw from <a href="https://access.redhat.com/security/cve/CVE-2013-0338">CVE-2013-0338</a>. Upstream patch: <a href="http://git.gnome.org/browse/libxml2/commit/?id=23f05e0c33987d6605387b300c4be5da2120a7ab">http://git.gnome.org/browse/libxml2/commit/?id=23f05e0c33987d6605387b300c4be5da2120a7ab</a>
