Description D'juan McDonald (domhnall) 2017-11-06 00:22:04 UTC

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.

@maintainer(s), after bump, please call stabilization when ready, thank you.
