The original misstatement (edited from lie, I don't think your being malicious, just uninformed):
Unfortunately SP2 has opened just as many holes as it closes, most worse than what they fixed.
What you posted to prove your point:
Cumulative Security Update for Internet Explorer for XP Service Pack 2 (KB890923)
The truth:
More FUD. The link you posted for is to address MS05-20. That exploit is on:
? Microsoft Windows 2000 Service Pack 3 and Microsoft Windows 2000 Service Pack 4
? Microsoft Windows XP Service Pack 1 and Microsoft Windows XP Service Pack 2
? Microsoft Windows XP 64-Bit Edition Service Pack 1 (Itanium)
? Microsoft Windows XP 64-Bit Edition Version 2003 (Itanium)
? Microsoft Windows Server 2003
? Microsoft Windows Server 2003 for Itanium-based Systems
? Microsoft Windows 98, Microsoft Windows 98 Second Edition (SE), and Microsoft Windows Millennium Edition (ME) Tested Microsoft Windows Components:
Your claim is that SP2 opens as many new holes as it's closes. You have yet to cite a single example.
Thank you for playing, please try again....
