This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu
14.04 LTS. (CVE-2014-5351)

It was discovered that the libgssapi_krb5 library incorrectly
processed security context handles. A remote attacker could use this
issue to cause a denial of service, or possibly execute arbitrary
code. (CVE-2014-5352)

Patrik Kis discovered that Kerberos incorrectly handled LDAP queries
with no results. An authenticated remote attacker could use this issue
to cause the KDC to crash, resulting in a denial of service.
(CVE-2014-5353)

It was discovered that Kerberos incorrectly handled creating database
entries for a keyless principal when using LDAP. An authenticated
remote attacker could use this issue to cause the KDC to crash,
resulting in a denial of service. (CVE-2014-5354)

It was discovered that Kerberos incorrectly handled memory when
processing XDR data. A remote attacker could use this issue to cause
kadmind to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2014-9421)

It was discovered that Kerberos incorrectly handled two-component
server principals. A remote attacker could use this issue to perform
impersonation attacks. (CVE-2014-9422)

It was discovered that the libgssrpc library leaked uninitialized
bytes. A remote attacker could use this issue to possibly obtain
sensitive information. (CVE-2014-9423).
