Mozilla Firefox: table use-after-free 

CVE-2017-5404


Mozilla bug tracker link: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1340138" title="" class="" rel="nofollow">https://bugzilla.mozilla.org/show_bug.cgi?id=1340138</a>

There is a use-after-free security vulnerability in Firefox. 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:
