libexif vulnerabilities




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
Ubuntu 7.04
Ubuntu 6.06

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