A heap-based-buffer-over-read flaw was found in ImageMagick's GetPixelAlpha() function of 'pixel-accessor.h'. This vulnerability is triggered when an attacker passes a specially crafted Tagged Image File Format (TIFF) image to convert it into a PICON file format. This issue can potentially lead to a denial of service and information disclosure.
In ImageMagick, a crafted file could trigger an assertion failure when a call to WriteImages was made in MagickWand/operation.c, due to a NULL image list. This could potentially cause a denial of service. This was fixed in upstream ImageMagick version 7.1.0-30.
A heap-use-after-free flaw was found in ImageMagick's RelinquishDCMInfo() function of dcm.c file. This vulnerability is triggered when an attacker passes a specially crafted DICOM image file to ImageMagick for conversion, potentially leading to information disclosure and a denial of service.
