GLSA-200411-21 : Samba: Multiple vulnerabilities

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

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.

Solution :

All Samba users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-fs/samba-3.0.8'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
