Ubuntu 4.10 : samba vulnerability (USN-22-1)

medium Nessus Plugin ID 20637

Synopsis

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

Description

Karol Wiesek discovered a Denial of Service vulnerability in samba. A flaw in the input validation routines used to match filename strings containing wildcard characters may allow a remote user to consume more than normal amounts of CPU resources, thus impacting the performance and response of the server. In some circumstances the server can become entirely unresponsive.

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.
