o Major bugfixes (HTTP, parsing): - When parsing a malformed content-length field from an HTTP message, do not read off the end of the buffer. This bug was a potential remote denial-of-service attack against Tor clients and relays. A workaround was released in October 2016, which prevents this bug from crashing Tor. This is a fix for the underlying issue, which should no longer matter (if you applied the earlier patch). Fixes bug 20894; bugfix on 0.2.0.16-alpha. Bug found by fuzzing using AFL (http://lcamtuf.coredump.cx/afl/).
