Security Vulnerabilities fixed in Firefox 85.0.1 and Firefox ESR 78.7.1 — Mozilla
In the Angle graphics library, depth pitch computations did not take into account the block size and simply multiplied the row pitch with the pixel height. This caused the load functions to use a very high depth pitch, reading past the end of the user-supplied buffer.Note: This issue only affecte...
