Subject: [USN-211-1] Enigmail vulnerability

===========================================================
Ubuntu Security Notice USN-211-1	   October 20, 2005
enigmail vulnerability
CVE-2005-3256
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

mozilla-enigmail
mozilla-thunderbird-enigmail

The problem can be corrected by upgrading the affected package to
version 2:0.92.1-0ubuntu04.10 (for Ubuntu 4.10), 2:0.92.1-0ubuntu05.04
(for Ubuntu 5.04), or 2:0.92.1-0ubuntu05.10 (for Ubuntu 5.10).  You
need to restart Thunderbird and Mozilla Mail after a standard system
upgrade to effect the necessary changes.

Details follow:

Hadmut Danish discovered an information disclosure vulnerability in
the key selection dialog of the Mozilla/Thunderbird enigmail plugin.
If a user's keyring contained a key with an empty user id (i. e. a
key without a name and email address), this key was selected by
default when the user attempted to send an encrypted email. Unless
this empty key was manually deselected, the message got encrypted for
that empty key, whose owner could then decrypt it.
