medium Nessus Plugin ID 27051

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-200710-16 (X.Org X server: Composite local privilege escalation)

Aaron Plattner discovered a buffer overflow in the compNewPixmap() function when copying data from a large pixel depth pixmap into a smaller pixel depth pixmap.
Impact :

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

Disable the Composite extension by setting ' Option 'Composite' 'disable' ' in the Extensions section of xorg.conf.
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-1.3.0.0-r1'
