"Samba developers discovered that nmbd could be made to overrun a
buffer during the processing of GETDC logon server requests. When
samba is configured as a Primary or Backup Domain Controller, a remote
attacker could send malicious logon requests and possibly cause a
denial of service. (CVE-2007-4572)

Alin Rad Pop of Secunia Research discovered that Samba did not
properly perform bounds checking when parsing SMB replies. A remote
attacker could send crafted SMB packets and execute arbitrary code.
(CVE-2008-1105).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
