Red Hat Security Advisory 2012-0465-01 - 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 flaw in the Samba suite's Perl-based DCE/RPC IDL compiler, used to generate code to handle RPC calls, resulted in multiple buffer overflows in Samba. A remote, unauthenticated attacker could send a specially-crafted RPC request that would cause the Samba daemon to crash or, possibly, execute arbitrary code with the privileges of the root user.
