Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
It was discovered that Kerberos did not correctly free memory in the
GSSAPI and kdb libraries. If a remote attacker were able to manipulate
an application using these libraries carefully, the service could
crash, leading to a denial of service. (Only Ubuntu 6.06 LTS was
affected.) (CVE-2007-5902, CVE-2007-5971, CVE-2007-5972)
Joel Johnson, Brian Almeida, and Shawn Emery discovered that Kerberos
did not correctly verify certain packet structures. An unauthenticated
remote attacker could send specially crafted traffic to cause the KDC
or kadmind services to crash, leading to a denial of service.
Update the affected packages.
