NVD Description

Note: Versions mentioned in the description apply only to the upstream graphicsmagick package and not the graphicsmagick package as distributed by Alpine. See How to fix? for Alpine:3.13 relevant fixed versions and status.

The ReadWPGImage function in coders/wpg.c in GraphicsMagick 1.3.26 does not properly validate colormapped images, which allows remote attackers to cause a denial of service (ImportIndexQuantumType invalid write and application crash) or possibly have unspecified other impact via a malformed WPG image.
