EulerOS 2.0 SP2 : samba (EulerOS-SA-2017-1105)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the samba packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- It was found that Samba always requested forwardable
tickets when using Kerberos authentication. A service
to which Samba authenticated using Kerberos could
subsequently use the ticket to impersonate Samba to
other services or domain users. (CVE-2016-2125)

- A flaw was found in the way Samba handled PAC
(Privilege Attribute Certificate) checksums. A remote,
authenticated attacker could use this flaw to crash the
winbindd process. (CVE-2016-2126)

- A race condition was found in samba server. A malicious
samba client could use this flaw to access files and
directories, in areas of the server file system not
exported under the share definitions. (CVE-2017-2619)

- A remote code execution flaw was found in Samba. A
malicious authenticated samba client, having write
access to the samba share, could use this flaw to
execute arbitrary code as root. (CVE-2017-7494)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
