CVE-2020-25665

A flaw was found in the PALM image coder at coders/palm.c where it makes an improper call to AcquireQuantumMemory() in the WritePALMImage() routine because it needs to be offset by 256. This issue causes an out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). 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 .
