Ubuntu 4.10 : krb5 vulnerability (USN-58-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Michael Tautschnig discovered a possible buffer overflow in the
add_to_history() function in the MIT Kerberos 5 implementation.
Performing a password change did not properly track the password
policy's history count and the maximum number of keys. This could
cause an array overflow and may have allowed authenticated users (not
necessarily one with administrative privileges) to execute arbitrary
code on the KDC host, compromising an entire Kerberos realm.

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 : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
