Microsoft acknowledged Thursday that one of the critical network vulnerabilities it patched earlier in the week was due to a programming error on its part.
The flaw, one of 34 patched Tuesday in a massive security update, was in the code for SMB 2 (Server Message Block 2), a Microsoft-made network file- and print-sharing protocol that ships with Windows Vista, Windows 7 and Windows Server 2008.
"Look at the two array references to ValidateRoutines[] near the end," said Michael Howard, principal security program manager in Microsoft's security engineering and communications group, referring to a code snippet he showed in a post to the Security Development Lifecycle (SDL) blog. "The array index to both is the wrong variable: pHeader->Command should be pWI->Command."
