Ubuntu Security Notice USN-156-1        July 29, 2005
tiff vulnerability
https://bugzilla.ubuntu.com/show_bug.cgi?id=12008
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

libtiff4

The problem can be corrected by upgrading the affected package to
version 3.6.1-1.1ubuntu1.4 (for Ubuntu 4.10), or 3.6.1-5ubuntu0.2 (for
Ubuntu 5.04). After a standard system upgrade you need to restart
your CUPS server with

  sudo /etc/init.d/cupsys restart

  to effect the necessary changes.


Details follow:

Wouter Hanegraaff discovered that the TIFF library did not
sufficiently validate the "YCbCr subsampling" value in TIFF image
headers. Decoding a malicious image with a zero value resulted in an
arithmetic exception, which caused the program that uses the TIFF
library to crash. This leads to a Denial of Service in server
applications that use libtiff (like the CUPS printing system) and can
cause data loss in, for example, the Evolution email client.

Updated packages for Ubuntu 4.10 (Warty Warthog):
