Last modified Jun 17, 2026

CVE-2017-16546 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. The ReadWPGImage function in coders/wpg.c in ImageMagick 7.0.7-9 does not properly validate the colormap index in a WPG palette, which allows remote attackers to cause a denial of service (use of uninitialized data or invalid memory allocation) or possibly have unspecified other impact via a malformed WPG file.. EPSS estimates a 2.20% chance of exploitation in the next 30 days.
