Red Hat Security Advisory 2016-0006-01 – Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. A denial of service flaw was found in the LDAP server provided by the AD DC in the Samba process daemon. A remote attacker could exploit this flaw by sending a specially crafted packet, which could cause the server to consume an excessive amount of memory and crash. Multiple buffer over-read flaws were found in the way Samba handled malformed inputs in certain encodings. An authenticated, remote attacker could possibly use these flaws to disclose portions of the server memory.
