low Nessus Plugin ID 56594

Language:

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-201110-19 (X.Org X Server: Multiple vulnerabilities)

 vladz reported the following vulnerabilities in the X.Org X server:
 The X.Org X server follows symbolic links when trying to access the lock file for a X display, showing a predictable behavior depending on the file type of the link target (CVE-2011-4028).
 The X.Org X server lock file mechanism allows for a race condition to cause the X server to modify the file permissions of an arbitrary file to 0444 (CVE-2011-4029).
 Impact :

 A local attacker could exploit these vulnerabilities to disclose information by making arbitrary files on a system world-readable or gain information whether a specified file exists on the system and whether it is a file, directory, or a named pipe.
 Workaround :

 There is no known workaround at this time.

Solution

All X.Org X Server 1.9 users should upgrade to the latest 1.9 version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-base/xorg-server-1.9.5-r1' All X.Org X Server 1.10 users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-base/xorg-server-1.10.4-r1'
