Mandriva Linux Security Advisory MDVSA-2013:198
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libxml2
Date : July 24, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in libxml2:

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) (CVE-2013-0339). This a different flaw from CVE-2013-0338.

parser.c in libxml2 before 2.9.0, as used in Google Chrome before
28.0.1500.71 and other products, allows remote attackers to cause
a denial of service (out-of-bounds read) via a document that ends
abruptly, related to the lack of certain checks for the XML_PARSER_EOF
state (CVE-2013-2877).

The updated packages have been patched to correct these issues.
