high Nessus Plugin ID 61109
New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon. These xorg-x11 packages also provide the X.Org libXfont runtime library.

A buffer overflow flaw was found in the way the libXfont library, used by the X.Org server, handled malformed font files compressed using UNIX compress. A malicious, local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server. (CVE-2011-2895)

Users of xorg-x11 should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running X.Org server instances must be restarted for the update to take effect.

Solution

Update the affected packages.
