CVE-2018-16853 – Slackware Security Advisory - samba Updates
https://notcve.org/view.php?id=CVE-2018-16853
28 Nov 2018 — Samba from version 4.7.0 has a vulnerability that allows a user in a Samba AD domain to crash the KDC when Samba is built in the non-default MIT Kerberos configuration. With this advisory the Samba Team clarify that the MIT Kerberos build of the Samba AD DC is considered experimental. Therefore the Samba Team will not issue security patches for this configuration. Additionally, Samba 4.7.12, 4.8.7 and 4.9.3 have been issued as security releases to prevent building of the AD DC with MIT Kerberos unless --wit... • http://www.securityfocus.com/bid/106026 • CWE-400: Uncontrolled Resource Consumption •

CVE-2018-16851 – Debian Security Advisory 4345-1
https://notcve.org/view.php?id=CVE-2018-16851
27 Nov 2018 — Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service. Samba, desd... • http://www.securityfocus.com/bid/106027 • CWE-476: NULL Pointer Dereference •

CVE-2018-16841 – Debian Security Advisory 4345-1

27 Nov 2018 — Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the ... • http://www.securityfocus.com/bid/106023 • CWE-415: Double Free CWE-416: Use After Free •
