I'm surprised by CGI. The vulnerability description talks about a second request being affected by corrupted state from an earlier request. But I thought CGI only processes one request per process?

		Iirc one of the main performance tricks for CGI was to get processes to stay alive. But there were two vulns - only the second required the two requests.
