Description

The remote host is affected by the vulnerability described in GLSA-200411-21 (Samba: Multiple vulnerabilities)

Samba fails to do proper bounds checking when handling     TRANSACT2_QFILEPATHINFO replies. Additionally an input validation flaw     exists in ms_fnmatch.c when matching filenames that contain wildcards.

Impact :

An attacker may be able to execute arbitrary code with the permissions     of the user running Samba. A remote attacker may also be able to cause     an abnormal consumption of CPU resources, resulting in slower     performance of the server or even a Denial of Service.

Workaround :

There is no known workaround at this time.
