The X Window System is a graphical windowing system based on a client/server model.
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"
OS | Version | Architecture | Package | Version | Filename |
---|---|---|---|---|---|
Gentoo | any | all | x11-base/xorg-server | < 1.1.1-r4 | UNKNOWN |
