An Emacs security update has been released for Ubuntu Linux 4.10

==========================================================
Ubuntu Security Notice USN-76-1 February 07, 2005
emacs21 vulnerability
CAN-2005-0100
==========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

emacs21-bin-common

The problem can be corrected by upgrading the affected package to version 21.3+1-5ubuntu4.2. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Max Vozeler discovered a format string vulnerability in the "movemail" utility of Emacs. By sending specially crafted packets, a malicious POP3 server could cause a buffer overflow, which could have been exploited to execute arbitrary code with the privileges of the user and the "mail" group (since "movemail" is installed as "setgid mail").
