Description Andrej Nemec 2016-12-20 09:12:41 UTC
It was found that there is an issue with parsing that could ause clients to read a single byte past the end of an allocated region. This bug could be used to cause hardened clients (built with --enable-expensive-hardening) to crash if they tried to visit a hostile hidden service. Non-hardened clients are only affected depending on the details of their platform's memory allocator.
