[Martin Pitt]

===========================================================
Ubuntu Security Notice USN-240-1	   January 11, 2006
bogofilter vulnerability
CVE-2005-4591
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

bogofilter

The problem can be corrected by upgrading the affected package to
version 0.95.2-1ubuntu1.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

A buffer overflow was found in bogofilter's character set conversion
handling. Certain invalid UTF-8 character sequences caused an invalid
memory access. By sending a specially crafted email, a remote attacker
could exploit this to crash bogofilter or possibly even execute
arbitrary code with bogofilter's privileges.
