It was discovered that Kerberos incorrectly handled certain malformed KRB5PADATAPKASREQ AS-REQ requests. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1415)

It was discovered that Kerberos incorrectly handled certain crafted TGS-REQ requests. A remote authenticated attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1416)

It was discovered that Kerberos incorrectly handled certain crafted requests when multiple realms were configured. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1418, CVE-2013-6800)

It was discovered that Kerberos incorrectly handled certain invalid tokens. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be used to cause the daemon to crash, resulting in a denial of service. (CVE-2014-4341, CVE-2014-4342)

It was discovered that Kerberos incorrectly handled certain mechanisms when used with SPNEGO. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be used to cause clients to crash, resulting in a denial of service. (CVE-2014-4343)

It was discovered that Kerberos incorrectly handled certain continuation tokens during SPNEGO negotiations. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. (CVE-2014-4344)

Tomas Kuthan and Greg Hudson discovered that the Kerberos kadmind daemon incorrectly handled buffers when used with the LDAP backend. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-4345)
