Ubuntu 4.10 / 5.04 / 5.10 : enigmail vulnerability (USN-211-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

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.

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.

Solution :

Update the affected mozilla-enigmail and / or
mozilla-thunderbird-enigmail packages.

Risk factor :

Medium / CVSS Base Score : 5.0
