This issue allows local attackers to gain access to the machine trust account of affected computers. Attackers may then impersonate the affected server in the domain. By impersonating the member server, attackers may gain access to further sensitive information, including the users and groups in the domain; other information may also be available. This may aid attackers in further attacks.
Samba versions 3.0.21 through to 3.0.21c that use the 'winbindd' daemon are susceptible to this issue.
