RHSA-2008:0064 - Security Advisory

Synopsis

Important: libXfont security update

Type/Severity

Security Advisory: Important

Topic

An updated X.Org libXfont package that fixes a security issue is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

The libXfont package contains the X.Org X11 libXfont runtime library.

A heap based buffer overflow flaw was found in the way the X.Org server
handled malformed font files. A malicious local user could exploit this
issue to potentially execute arbitrary code with the privileges of the
X.Org server. (CVE-2008-0006)

Users of X.Org libXfont should upgrade to these updated packages, which
contain a backported patch to resolve this issue.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
