medium Nessus Plugin ID 64964
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 Scientific Linux host is missing one or more security updates.

Description

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)

The desktop must be restarted (log out, then log back in) for this update to take effect.

Solution

Update the affected packages.
