Description Pedro Sampaio 2017-09-22 13:05:00 UTC
DrawGetStrokeDashArray in wand/drawing-wand.c in ImageMagick 7.0.7-1 mishandles certain NULL arrays, which allows attackers to perform Denial of Service (NULL pointer dereference and application crash in AcquireQuantumMemory within MagickCore/memory.c) by providing a crafted Image File as input.
