Synopsis:          Moderate: samba4 security and bug fix update
Advisory ID:       SLSA-2017:0744-1
Issue Date:        2017-03-21
CVE Numbers:       CVE-2016-2125
                   CVE-2016-2126
--

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)
