An optimization in WebGL was incorrect in some cases, and could have led to
memory corruption and a potentially exploitable crash. Note: This
advisory was added on December 13th, 2022 after we better understood the
impact of the issue. The fix was included in the original release of
Firefox 106. This vulnerability affects Firefox < 106, Firefox ESR < 102.6,
and Thunderbird < 102.6.
