Added a section to the blog post explaining it in broad strokes:
## tl;dr * A carefully crafted attack request can cause the contents of the HTTP parser’s buffer to be appended to the attacking request’s header, making it appear to come from the attacker. Since it is generally safe to echo back contents of a request, this can allow an attacker to get an otherwise correctly designed server to divulge information about other requests. It is theoretically possible that it could enable header-spoofing attacks. * Versions affected: All versions of the 0.5/0.6 branch prior to 0.6.17, and all versions of the 0.7 branch prior to 0.7.8. Versions in the 0.4 branch are not affected. * Fix: Upgrade to v0.6.17, or apply the fix in c9a231d to your system.
