Subject: [USN-654-1] libexif vulnerabilities

===========================================================
Ubuntu Security Notice USN-654-1           October 14, 2008
libexif vulnerabilities
CVE-2007-6351, CVE-2007-6352
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libexif12                       0.6.12-2ubuntu0.3

Ubuntu 7.04:
  libexif12                       0.6.13-5ubuntu0.3

Ubuntu 7.10:
  libexif12                       0.6.16-1ubuntu0.1

After a standard system upgrade you need to restart your session to effect
the necessary changes.

Details follow:

Meder Kydyraliev discovered that libexif did not correctly handle certain
EXIF headers.  If a user or automated system were tricked into processing
a specially crafted image, a remote attacker could cause the application
linked against libexif to crash, leading to a denial of service, or
possibly executing arbitrary code with user privileges.


Updated packages for Ubuntu 6.06 LTS:
