Mozilla community member Philipp reported a memory safety bug present in
Firefox 68 when 360 Total Security was installed. This bug showed evidence
of memory corruption in the accessibility engine and we presume that with
enough effort that it could be exploited to run arbitrary code. This
vulnerability affects Firefox < 69, Thunderbird < 68.2, and Firefox ESR <
68.2.
