Johannes Ullrich Tested Quotations

We carefully checked this patch and are 100 percent sure that it is not malicious. The patch is, of course, not as carefully tested as an official patch. But we feel it is worth the risk. We know it blocks all exploit attempts we are aware of.

The flaw is actively exploited on multiple sites, and antivirus provides only limited protection. Active use of an exploit without sufficient mitigating measures should warrant the early release of a patch, even a preliminary, not fully tested patch.
