Problems with MS06-042 (KB918899) and web sites that use the HTTP 1.1 protocol and compression
We've seen a number of reports since (Patch) Tuesday from folks running either Windows 2000 or Windows XP SP1 that IE is crashing when accessing certain sites, most notably PeopleSoft applications. It was (strongly) suspected that MS06-042 (KB918899) was causing the problem - for most people, uninstalling the patch made the problem go away.
A couple of workarounds were posted, one requiring a server setting change, the other required a browser setting change.
Late this afternoon, Microsoft announced the availability of a hotfix for this problem.
