Comment (by nickm):

 My branch `bug21018_024` has the fix.  From the changes file:
 {{{
 +    - Fix a bug in parsing that could cause 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. Fixes bug 21018; bugfix on 0.2.0.8-alpha. Found by
 +      using libFuzzer. Also tracked as TROVE-2016-12-002 and as
 +      CVE-2016-1254.
 }}}
