Microsoft Security Response Center Blog re-released the new version of MS08-030 security update for Windows XP SP2 and SP3 customers and to encourage them to deploy these new updates. There are no new updates for the other versions of Windows discussed in the bulletin.
After we released MS08-030 we learned that the security updates for Windows XP SP2 and SP3 might not have been fully protecting against the issues discussed in that bulletin. As soon as we learned of that possibility, we mobilized our Software Security Incident Response Process (SSIRP) to investigate the issue.
Our investigation found that while the other security updates were providing protections for the issues discussed in the bulletin, the Windows XP SP2 and SP3 updates were not.
