This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200701-25
(X.Org X server: Multiple vulnerabilities)

Multiple memory corruption vulnerabilities have been found in the
ProcDbeGetVisualInfo() and the ProcDbeSwapBuffers() of the DBE
extension, and ProcRenderAddGlyphs() in the Render extension.

Impact :

A local attacker could execute arbitrary code with the privileges of
the user running the X server, typically root.

Workaround :

Disable the DBE extension by removing the 'Load dbe' directive in the
Module section of xorg.conf, and explicitly disable the Render
extension with ' Option 'RENDER' 'disable' ' in the Extensions section.
Note: This could affect the functionality of some applications.
