medium Nessus Plugin ID 63106
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 heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5134)

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

Solution

Update the affected packages.
