"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."
