Description:
Karol Wiesek has reported a vulnerability in Samba, which can be exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to an input validation error within the "ms_fnmatch()" function when matching filenames containing wildcard characters. This can be exploited via multiple specially crafted commands to consume a large amount of CPU resources.

Successful exploitation may cause the server to stop responding entirely.

The vulnerability affects version 3.0.7 and prior.
