Ubuntu 5.04 / 5.10 / 6.06 LTS : samba vulnerability (USN-314-1)

medium Nessus Plugin ID 27890

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

The Samba security team reported a Denial of Service vulnerability in the handling of information about active connections. In certain circumstances an attacker could continually increase the memory usage of the smbd process by issuing a large number of share connection requests. By draining all available memory, this could be exploited to render the remote Samba server unusable.

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 packages.
