(MS09-050) Vulnerabilities in SMBv2 Could Allow Remote Code Execution (975517)
Descripción
This update resolves three reported vulnerabilities in Server Message Block Version 2 (SMBv2) -- one publicly disclosed and two in private. Successful exploitation of the said vulnerabilities could lead to different results, including remote code execution.
This update correctly validates the fields inside SMBv2 packets, which corrects the way SMB handles the command value in SMB packets and the way SMB parses specially crafted SMB packets.
Installing standard firewall protection is advised to help protect networks from attacks.
