Description

ImageMagick before 7.1.2-35 and 6.9.13-60 contains an infinite loop vulnerability in the SVG decoder because QueueAuthenticPixelCacheNexus in MagickCore/cache.c fails to validate requested region width and height. Attackers can supply a crafted SVG image that repeatedly requests a non-advancing pixel region, consuming CPU and hanging the decoding worker.
