Title: X.Org X server: Multiple vulnerabilities (GLSA 200701-25)
Date: January 27, 2007
Updated: February 26, 2007
Sean Larsson from iDefense Labs has found multiple vulnerabilities in the
DBE and Render extensions.
The X Window System is a graphical windowing system based on a
Vulnerable: < 1.1.1-r4
Unaffected: >= 1.1.1-r4
Architectures: All supported architectures
Multiple memory corruption vulnerabilities have been found in the
ProcDbeGetVisualInfo() and the ProcDbeSwapBuffers() of the DBE
extension, and ProcRenderAddGlyphs() in the Render extension.
A local attacker could execute arbitrary code with the privileges of
the user running the X server, typically root.
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.
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"
