Description Pedro Sampaio 2017-12-14 18:04:01 UTC

In ImageMagick 7.0.7-12 Q16, a large loop vulnerability was found in the
function ExtractPostscript in coders/wpg.c, which allows attackers to cause a
denial of service (CPU exhaustion) via a crafted wpg image file that triggers a
ReadWPGImage call.
