Title:RedHat Update for samba RHSA-2017:1265-01
Summary:The remote host is missing an update for the 'samba'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'samba'
package(s) announced via the referenced advisory.

Vulnerability Insight:
Samba is an open-source implementation of
the Server Message Block (SMB) protocol and the related Common Internet File
System (CIFS) protocol, which allow PC-compatible machines to share files,
printers, and various information.

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)
