a vulnerability as referenced in the mfsa2021-06 advisory.

  - 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. (CVE-2020-16048)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
