    A use-after-free vulnerability exists in the palette reduction

Impact :

    A remote attacker could entice a user to open a specially crafted image
      file, possibly resulting in  execution of arbitrary code with the
      privileges of the process or a Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."
