Red Hat Security Advisory 2013-1806-01 - 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 heap-based buffer overflow flaw was found in the DCE-RPC client code in Samba. A specially crafted DCE-RPC packet could cause various Samba programs to crash or, possibly, execute arbitrary code when parsed. A malicious or compromised Active Directory Domain Controller could use this flaw to compromise the winbindd daemon running with root privileges.
