libexif vulnerabilities

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

  • Ubuntu 7.10
  • Ubuntu 7.04
  • Ubuntu 6.06 LTS

Software Description

  • libexif

Details

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.

Update instructions

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

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.
