New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.

Solution

Update the affected packages.
