JLSEC-2026-871

A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to...

JLSEC-2026-881

A flaw was found in ImageMagick in MagickCore/visual-effects.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat from this vulnerability is to system availability...

JLSEC-2026-919 imagemagick: heap-buffer overflow read in MNG magnification with alpha

Vulnerability Details When performing image magnification in ReadOneMNGIMage in coders/png.c, there is an issue around the handling of images with separate alpha channels. When loading an image with a color type that implies a separate alpha channel ie. jngcolortype = 12, we will load the alpha...

JLSEC-2026-920

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, when preparing to transform from Log to sRGB colorspaces, the logmap construction fails to handle cases where the reference-black or reference-white value is larger than 1024...

JLSEC-2026-895

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...

JLSEC-2026-1066 ImageMagick before 7.1.2-26 and 6.9.13-51 contains a use-after-free vulnerability that occurs...

ImageMagick before 7.1.2-26 and 6.9.13-51 contains a use-after-free vulnerability that occurs when freetype initialization fails: the method does not exit and continues to use memory that was already freed. This can be triggered during image processing and may lead to a denial of service...

JLSEC-2026-923 ImageMagick affected by divide-by-zero in ThumbnailImage via montage -geometry ":" leads to crash

Summary Passing a geometry string containing only a colon ":" to montage -geometry leads GetGeometry to set width/height to 0. Later, ThumbnailImage divides by these zero dimensions, triggering a crash SIGFPE/abort, resulting in a denial of service. Details Root Cause 1. montage -geometry ":"...

JLSEC-2026-1013 ImageMagick: Heap Buffer Over-Write in MIFF encoder when using LZMA compression

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, when using LZMA compression in the MIFF encoder an out of bounds write can occur due to a missing check. This issue has been patched in versions 6.9.13-48 and...

JLSEC-2026-981 ImageMagick: Integer overflow in DIB coder can result in out of bounds read or write

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, an integer overflow in DIB coder can result in out of bounds read or write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41...

JLSEC-2026-921 imagemagick: integer overflows in MNG magnification

Vulnerability Details The magnified size calculations in ReadOneMNGIMage in coders/png.c are unsafe and can overflow, leading to memory corruption. The source snippet below is heavily abbreviated due to the size of the function, but hopefully the important points are captured. c static Image...

JLSEC-2026-958 ImageMagick: MSL - Stack overflow in ProcessMSLScript
