Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Sean Larsson of iDefense Labs discovered that the MISC-XC extension of
Xorg did not correctly verify the size of allocated memory. An
authenticated user could send a specially crafted X11 request and
execute arbitrary code with root privileges. (CVE-2007-1003)

Greg MacManus of iDefense Labs discovered that the BDF font handling
code in Xorg and FreeType did not correctly verify the size of
allocated memory. If a user were tricked into using a specially
crafted font, a remote attacker could execute arbitrary code with root
privileges. (CVE-2007-1351, CVE-2007-1352).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
