It was discovered that the Samba internal DNS server incorrectly handled QR
fields when processing incoming DNS messages. A remote attacker could use
this issue to cause Samba to consume resources, resulting in a denial of
service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0239)

Daniel Berteaud discovered that the Samba NetBIOS name service daemon
incorrectly handled certain malformed packets. A remote attacker could use
this issue to cause Samba to consume resources, resulting in a denial of
service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
Ubuntu 14.04 LTS. (CVE-2014-0244)

Simon Arlott discovered that Samba incorrectly handled certain unicode path
