Ubuntu 6.06 LTS / 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : postfix vulnerability (USN-1131-1)

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


Synopsis :

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

Description :

Thomas Jarosch discovered that Postfix incorrectly handled
authentication mechanisms other than PLAIN and LOGIN when the Cyrus
SASL library is used. A remote attacker could use this to cause
Postfix to crash, leading to a denial of service, or possibly execute
arbitrary code as the postfix user.

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 postfix package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.0
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
