Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 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.

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
