Ubuntu Security Notice USN-654-1
14th October, 2008
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.10
- Ubuntu 7.04
- Ubuntu 6.06 LTS
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 7.10:
- libexif12 0.6.16-1ubuntu0.1
- Ubuntu 7.04:
- libexif12 0.6.13-5ubuntu0.3
- Ubuntu 6.06 LTS:
- libexif12 0.6.12-2ubuntu0.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart your session to effect
the necessary changes.
