REDHAT-BUG-912400
First published: Mon Feb 18 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 entity references replacement (--noent option) was requested / enabled during the XML file parsing. A remote attacker could provide a specially-crafted XML file that, when processed would lead to excessive CPU consumption (denial of service).
