In ImageMagick, there are 3 outside the range of representable values of type 'unsigned char' at coders/hdr.c.
Name: Suhwan Song (Seoul National University)
`WriteHDRImage()` in /coders/hdr.c could attempt to set unsigned chars to values outside of range, depending on pixel color values. The patch adds checks for > 0 to ensure that this does not occur. The flaw could be triggered by a crafted input file that is processed by ImageMagick. 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 shown in this case.
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 .
