Details

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. (CVE-2010-1320,
CVE-2010-1321)
