Mozilla Firefox before 55.0 :- Mozilla developers and community members Gary Kwong, Christian Holler, Andre Bargull, Bob Clary, Carsten Book, Emilio Cobos Alvarez, Masayuki Nakano, Sebastian Hengst, Franziskus Kiefer, Tyson Smith, and Ronald Crane reported memory safety bugs present in Firefox. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
