Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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.
