high Nessus Plugin ID 61218
New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

The libxml2 library is a development toolbox providing the implementation of various XML standards.

A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. 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-2011-3919)

An out-of-bounds memory read flaw was found in libxml2. 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. (CVE-2011-3905)

All users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect.

Solution

Update the affected packages.
