GLSA-200701-25 : X.Org X server: Multiple vulnerabilities

critical Nessus Plugin ID 24310

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.

Solution

All X.Org X server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=x11-base/xorg-server-1.1.1-r4'
