Memory safety bugs present in Firefox 61 and Firefox ESR 60.1. 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.
This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and
Thunderbird < 60.2.1.
