(Snack: User-assisted execution of arbitrary code)

    The GetWavHeader() function in jkSoundFile.c does not have boundary
      checks when parsing format sub-chunks or unknown sub-chunks.
  
Impact :

    A remote attacker could entice a user to open a specially crafted WAV
      file with an application using Snack, possibly resulting in execution of
      arbitrary code or a Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."
