No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.
