CVE-2020-25674

A flaw was found in ImageMagick. When the colormap has less than 256 valid values, the loop condition will continue to loop 256 times, attempting to pass invalid colormap data to the event logger, leading to an improper exit condition and an out-of-bounds read via heap-buffer-overflow. The highest threat from this vulnerability is to system availability.

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.
