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

Vulnerability Assessment Summary
X.Org X server: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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 rights of
the user running the X server, typically root.

Workaround

Disable the dbe and render extension by removing the "Load dbe" and
"Load render" directives in the Module section of xorg.conf.
Note: This could affect the functionality of some applications.
