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


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

Security Fix(es) :

- 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)
