Ubuntu 10.04 LTS / 10.10 : krb5 vulnerability (USN-999-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Mike Roszkowski discovered that the Kerberos KDC did not correctly
validate the contents of certain messages. If an authenticated remote
attacker sent specially crafted TGS requests, the KDC service would
crash, leading to a denial of service.

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 packages.

Risk factor :

Medium / CVSS Base Score : 6.5
(CVSS2#AV:N/AC:L/Au:S/C:P/I:P/A:P)
