A buffer overflow can occur when rendering canvas content while adjusting
the height and width of the canvas element dynamically, causing data to be
written outside of the currently computed boundaries. This results in a
potentially exploitable crash. This vulnerability affects Thunderbird < 60,
Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox <
61.
