CVE-2020-6821

Priority
Description
When reading from areas partially or fully outside the source resource with
WebGL's <code>copyTexSubImage</code> method, the specification requires the
returned values be zero. Previously, this memory was uninitialized, leading
to potentially sensitive data disclosure. This vulnerability affects
Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
