Comment 7 Riccardo Schirone 2021-03-16 16:28:59 UTC 
Statement:

This issue did not affect the versions of python-pillow as shipped with Red Hat Enterprise Linux 8 as they did not include the vulnerable code, which was introduced in a newer upstream version than what what shipped.

Disable the invoice generation feature to mitigate this vulnerability in Red Hat Quay.
