Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that Dovecot incorrectly validated certificate
hostnames when being used as a POP3 and IMAP proxy. If a remote
attacker were able to perform a man-in-the-middle attack, this flaw
could be exploited to view sensitive information.

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 dovecot-common package.
