Vulnerability Assessment Details

[GLSA-200411-21] Samba: Multiple vulnerabilities

Vulnerability Assessment Summary
Samba: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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

A possible hacker 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.
