High (8.1) in imagemagick imagemagick. EPSS 4.1% chance of exploitation in the next 30 days.
In ImageMagick 7.0.8-40 Q16, there is a heap-based buffer over-read in the function WritePNMImage of coders/pnm.c, which allows an attacker to cause a denial of service or possibly information disclosure via a crafted image file. This is related to SetGrayscaleImage in MagickCore/quantize.c.
