Emacs vulnerability

Releases

Packages

Details

Hendrik Tews discovered that emacs21 did not correctly handle certain
GIF images. By tricking a user into opening a specially crafted GIF,
a remote attacker could cause emacs21 to crash, resulting in a denial
of service.

Update instructions

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

Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

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