  o Minor bugfixes (fuzzing):
    - Fix a bug in our fuzzing mock replacement for crypto_pk_checksig(), to
      correctly handle cases where a caller gives it an RSA key of under 160
      bits. (This is not actually a bug in Tor itself, but wrather in our
      fuzzing code.)  Fixes bug 24247; bugfix on 0.3.0.3-alpha.
      Found by OSS-Fuzz as issue 4177.
Fix mock_crypto_pk_public_checksig__nocheck() to handle short RSA keys This function -- a mock replacement used only for fuzzing -- would have a buffer overflow if it got an RSA key whose modulus was under 20 bytes long. Fortunately, Tor itself does not appear to have a bug here. Fixes bug 24247; bugfix on 0.3.0.3-alpha when fuzzing was introduced. Found by OSS-Fuzz; this is OSS-Fuzz issue 4177. 2017-11-11 20:42:39 +01:00			`o Minor bugfixes (fuzzing):`
