Test ID:1.3.6.1.4.1.25623.1.0.59136
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-448-1 (xorg-server)
Summary:Ubuntu USN-448-1 (xorg-server)
Description:
The remote host is missing an update to xorg-server
announced via advisory USN-448-1.

A security issue affects the following Ubuntu releases:

Ubuntu 5.10
Ubuntu 6.06 LTS
Ubuntu 6.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

Details follow:

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)
