libopenmpt 0.5.11 (2021-08-22)

  • [Sec] Possible crash with malformed modules when trying to access non-existent plugin slots FX251-FX255. (r15479, r15518)
  • [Sec] Possible read beyond sample start after swapping to a sample with loop points set but not loop enabled. (r15499)
  • [Sec] Fixed various possible crashes with malformed MMCMP files. (r15504, 15528)

  • [Sec] MED: Possible read past end of sequence name (stack-allocated, so relatively unlikely to result in a crash). (r15477)

  • Fixed excessive memory usage with files claiming to have an extremely high rows per beat count while also using tempo swing. Maximum rows per beat are now limited to 65536.

  • STP: Avoid creating thousands of patterns when loading malformed files even though no more pattern data can be read.

  • mpg123: Update to v1.28.2 (2021-07-12).
