[tor.git] / changes / microdesc-double-free

  o Security fixes:
    - Don't double-free a parsable, but invalid, microdescriptor, even
      if it is followed in the blob we're parsing by an unparsable
      microdescriptor.  Fixes an issue reported in a comment on bug 2954.
      Bugfix on 0.2.2.6-alpha; fix by "cypherpunks".
