Comment 2 Todd Cullum 2020-11-05 23:00:08 UTC 
The patch addresses several occurrences in `PosterizeImage()`. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was demonstrated in this case.
Comment 3 Todd Cullum 2020-11-05 23:00:21 UTC 
Statement:

This flaw is out of support scope for Red Hat Enterprise Linux 5, 6, and 7. Inkscape is not affected because it no longer uses a bundled ImageMagick in Red Hat Enterprise Linux 8. For more information regarding support scopes, please see https://access.redhat.com/support/policy/updates/errata .
Comment 4 Guilherme de Almeida Suckevicz 2020-11-24 19:28:21 UTC
