nginx: NGINX: Heap buffer over-read allows memory modification or denial of service

A vulnerability in NGINX's ngxhttpssimodule allows an unauthenticated MITM attacker to trigger a heap buffer over-read by manipulating upstream server responses. This requires SSI, proxypass, and proxybuffering off to be configured, and can result in memory modification or a Denial of Service DoS...
