The August patch for MS06-042 have been known to cause Internet Explorer to crash while browsing sites with HTTP 1.1 compression on Windows XP Service Pack 1 and Windows 2000.
On August 22, eEye Digital Security released a posting expressing that this is not just a bug that crashes Internet Explorer but is actually an exploitable one. Ironically, it’s an exploitable vulnerability in a vulnerability patch.
No worries though as Microsoft has already re-released the MS06-042 patch to fix the issue. So people, patch your systems!
