Mozilla developers and community members reported memory safety bugs
present in Firefox 72 and Firefox ESR 68.4. Some of these bugs showed
evidence of memory corruption and we presume that with enough effort some
of these could have been exploited to run arbitrary code. In general, these
flaws cannot be exploited through email in the Thunderbird product because
scripting is disabled when reading mail, but are potentially risks in
browser or browser-like contexts. This vulnerability affects Thunderbird <
68.5, Firefox < 73, and Firefox < ESR68.5.
