Description Pedro Sampaio 2017-09-01 17:36:02 UTC

GraphicsMagick 1.3.26 has a denial of service issue in ReadXBMImage()
in a coders/xbm.c "Read hex image data" version!=10 case that results
in the reader not returning; it would cause large amounts of CPU and
memory consumption although the crafted file itself does not request
it.
