Mandriva Linux Security Advisory : libxml2 (MDVSA-2013:056)

medium Nessus Plugin ID 66070
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 was found and corrected in libxml2 :

A heap-buffer overflow was found in the way libxml2 decoded certain XML entitites. A remote attacker could provide a specially crafted XML file, which once opened in an application linked against libxml would cause that application to crash, or, potentially, execute arbitrary code with the privileges of the user running the application (CVE-2012-5134).

A denial of service flaw was found in the way libxml2 performed string substitutions when entity values for entity references replacement was enabled. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, would lead to excessive CPU consumption (CVE-2013-0338).

An Off-by-one error in libxml2 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via unknown vectors (CVE-2011-3102).

Multiple integer overflows in libxml2, on 64-bit Linux platforms allow remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors (CVE-2012-2807).

The updated packages have been patched to correct these issues.

Solution

Update the affected packages.
