===========================================================
Ubuntu Security Notice USN-887-1           January 18, 2010
libthai vulnerability
CVE-2009-4012
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04
Ubuntu 9.10

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

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
  libthai0                        0.1.9-1ubuntu0.2

Ubuntu 8.10:
  libthai0                        0.1.9-4ubuntu0.8.10.2

Ubuntu 9.04:
  libthai0                        0.1.9-4ubuntu0.9.04.2

Ubuntu 9.10:
  libthai0                        0.1.12-1ubuntu0.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Tim Starling discovered that LibThai did not correctly handle long strings.
A remote attacker could use specially-formed strings to execute arbitrary
code with the user's privileges.
