Ubuntu 9.10 / 10.04 LTS / 10.10 : krb5 vulnerability (USN-1088-1)

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 :

Cameron Meadors discovered that the MIT Kerberos 5 Key Distribution
Center (KDC) daemon is vulnerable to a double-free condition if the
Public Key Cryptography for Initial Authentication (PKINIT) capability
is enabled. This could allow a remote attacker to cause 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 :

High / CVSS Base Score : 7.6
