Memory safety bugs were reported in Firefox 56 and Firefox ESR 52.4. 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 < 57, Firefox ESR < 52.5, and
Thunderbird < 52.5.
