Description

 A remote buffer overflow exists in Samba. The service fails to check a field length inside of the request before using this length in a memcpy() operation, resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code to be executed with super-user privileges, resulting in a loss of confidentiality and integrity.
