tiff vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

The TIFF library could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- tiff: Tag Image File Format (TIFF) library

Details:

It was discovered that the TIFF library incorrectly handled certain
malformed TIFF images. If a user or automated system were tricked into
opening a specially crafted TIFF image, a remote attacker could crash the
application, leading to a denial of service, or possibly execute arbitrary
code with user privileges. (CVE-2012-2088)

It was discovered that the tiff2pdf utility incorrectly handled certain
malformed TIFF images. If a user or automated system were tricked into
opening a specially crafted TIFF image, a remote attacker could crash the
application, leading to a denial of service, or possibly execute arbitrary
code with user privileges. (CVE-2012-2113)

Update instructions:
