Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : krb5 vulnerability (USN-881-1)

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 :

It was discovered that Kerberos did not correctly handle invalid AES
blocks. An unauthenticated remote attacker could send specially
crafted traffic that would crash the KDC service, leading to a denial
of service, or possibly execute arbitrary code with root privileges.

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 :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
