Samba Denial of Service Vulnerabilities

Multiple vulnerabilities have been identified in Samba, which can be exploited by malicious users to cause a DoS (Denial of Service).

1. An error in the "sys_recvfrom()" function (source3/lib/system.c) can be exploited to trigger an infinite loop within the nmbd daemon by sending a specially crafted NetBIOS packet.
2. Some errors when handling Unicode file names can be exploited to cause out-of-bounds writes and subsequently crash the smbd daemon by issuing a non-Unicode read request for such files.
