Ubuntu 10.04 LTS / 10.10 / 11.04 : mutt vulnerability (USN-1221-1)

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


Synopsis :

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

Description :

It was discovered that mutt incorrectly verified the hostname in an
SSL certificate. An attacker could trick mutt into trusting a rogue
SMTPS, IMAPS, or POP3S server's certificate, which was signed by a
trusted certificate authority, to perform a man-in-the-middle attack.

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 mutt and / or mutt-patched packages.

Risk factor :

Medium / CVSS Base Score : 5.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:N)
CVSS Temporal Score : 4.8
(CVSS2#E:F/RL:OF/RC:ND)
Public Exploit Available : true
