Description
An information disclosure issue has been found in Firefox before 75.0 and Thunderbird before 68.7.0. When reading from areas partially or fully outside the source resource with WebGL's copyTexSubImage method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure.
