#MOZ-2021-0001: Buffer overflow in depth pitch calculations for compressed
textures

Reporter: Abraruddin Khan and Omair working with Trend Micro Zero Day Initiative
Impact:   critical

Description

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 affected Windows operating systems. Other operating
systems are unaffected.
This issue has been assigned a temporary identifier, pending assignment of a
CVE.
