Ubuntu 6.06 LTS / 6.10 / 7.04 : emacs21 vulnerability (USN-504-1)

High Nessus Plugin ID 28108


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
