During HTTP Live Stream playback on Firefox for Android, audio data can be
accessed across origins in violation of security policies. Because the
problem is in the underlying Android service, this issue is addressed by
treating all HLS streams as cross-origin and opaque to access. Note: this
issue only affects Firefox for Android. Desktop versions of Firefox are
unaffected.. This vulnerability affects Firefox < 63, Firefox ESR < 60.3,
and Thunderbird < 60.3.
