Summary

Buffer overflow in the SMB1 packet chaining implementation in the chain_reply function in process.c in smbd in Samba 3.0.x before 3.3.13 allows remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a crafted field in a packet.
