Ubuntu 14.04 LTS / 14.10 : samba vulnerability (USN-2481-1)

High Nessus Plugin ID 80944


The remote Ubuntu host is missing a security-related patch.


Andrew Bartlett discovered that Samba incorrectly handled delegation of authority when being used as an Active Directory Domain Controller.
An attacker given delegation privileges could use this issue to escalate their privileges further.

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.


Update the affected samba package.
