A vulnerability has been discovered and corrected in samba: Samba versions 3.0.x, 3.2.x and 3.3.x are affected by a memory corruption vulnerability. Code dealing with the chaining of SMB1 packets did not correctly validate an input field provided by the client, making it possible for a specially crafted packet to crash the server or potentially cause the server to execute arbitrary code . Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program
