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

Description :

Keiichi Mori discovered that the MIT krb5 KDC database propagation
daemon (kpropd) is vulnerable to a denial of service attack due to
improper logic when a worker child process exited because of invalid
network input. This could only occur when kpropd is running in
standalone mode; kpropd was not affected when running in incremental
propagation mode ('iprop') or as an inetd server. This issue only
affects Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu 10.10.

Kevin Longfellow and others discovered that the MIT krb5 Key
Distribution Center (KDC) daemon is vulnerable to denial of service
attacks when using an LDAP back end due to improper handling of
network input. (CVE-2011-0281, CVE-2011-0282).

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.

Update the affected packages.
