"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
