Avoid loading OpenCV data structures from external untrusted JSON files.
Comment 5 Mauro Matteo Cascella 2020-04-20 13:27:49 UTC 
Statement:

This flaw did not affect the versions of OpenCV as shipped with Red Hat Enterprise Linux 6, 7, and 8, as they did not include the vulnerable code, which was introduced in a later version of the library.
