Other sources
Mozilla developers and community members Christoph Diehl, Andrew McCreight, Dan Minor, Byron Campen, Jon Coppeard, Steve Fink, Tyson Smith, Philipp, and Carsten Book reported memory safety bugs present in Firefox 48 and Firefox ESR 45.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
