CentOS Errata and Security Advisory CESA-2014:1885
The libxml2 library is a development toolbox providing the implementation
of various XML standards.
A denial of service flaw was found in libxml2, a library providing support
to read, modify and write XML and HTML files. A remote attacker could
provide a specially crafted XML file that, when processed by an application
using libxml2, would lead to excessive CPU consumption (denial of service)
based on excessive entity substitutions, even if entity substitution was
disabled, which is the parser default behavior. (CVE-2014-3660)
All libxml2 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. The desktop must be
restarted (log out, then log back in) for this update to take effect.
