Update Information:

A problem with PDF handling was discovered by Chris Evans, and has
been fixed.  The Common Vulnerabilities and Exposures project
(www.mitre.org) has assigned the name CAN-2004-0888 to this issue.

a number of buffer overflow bugs that affect libtiff have
been found. The kfax application contains a copy of the libtiff code used
for parsing TIFF files and is therefore affected by these bugs. An attacker
who has the ability to trick a user into opening a malicious TIFF file
could cause kfax to crash or possibly execute arbitrary code. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0803 to this issue.
