Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : samba vulnerability (USN-1434-1)

medium Nessus Plugin ID 58948

Language:

Synopsis

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

Description

Ivano Cristofolini discovered that Samba incorrectly handled some Local Security Authority (LSA) remote procedure calls (RPC). A remote, authenticated attacker could exploit this to grant administrative privileges to arbitrary users. The administrative privileges could be used to bypass permission checks performed by the Samba server.

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.

Solution

Update the affected samba package.
