  o Minor bugfixes (performance, DoS):
    - Fix one case of a not-especially viable denial-of-service attack found
      by OSS-Fuzz in our consensus-diff parsing code. This attack causes a
      lot small of memory allocations and then immediately frees them: this
      is only slow when running with all the sanitizers enabled.  Fixes one
      case of bug 40472; bugfix on 0.3.1.1-alpha.
Limit the number of elements in a consdiff hash line. This avoids performing and then freeing a lot of small mallocs() if the hash line has too many elements. Fixes one case of bug 40472; resolves OSS-Fuzz 38363. Bugfix on 0.3.1.1-alpha when the consdiff parsing code was introduced. 2021-12-06 18:35:08 +01:00			`o Minor bugfixes (performance, DoS):`
