JLSEC-2026-992 ImageMagick has an Out-of-bounds Write via InterpretImageFilename

Due to an incorrect return value on certain platforms a pointer is incremented past the end of a buffer that is on the stack and that could result in an out of bounds write. ================================================================= ==48558==ERROR: AddressSanitizer: stack-buffer-overflow o...

JLSEC-2026-949 ImageMagick has Division-by-Zero in YUV sampling factor validation, which leads to crash

A logic error in YUV sampling factor validation allows an invalid sampling factor to bypass checks and trigger a division-by-zero during image loading, resulting in a reliable denial-of-service. coders/yuv.c:210:47: runtime error: division by zero AddressSanitizer:DEADLYSIGNAL...

JLSEC-2026-965 ImageMagick: Integer overflow or wraparound and incorrect conversion between numeric types in the internal SVG decoder

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a crafted SVG file can cause a denial of service. An off-by-one boundary check instead of = that allows bypass the guard and reach an undefined sizet cast...

JLSEC-2026-886

A flaw was found in ImageMagick in versions before 7.0.11, where a division by zero in sRGBTransformImage in the MagickCore/colorspace.c may trigger undefined behavior via a crafted image file that is submitted by an attacker processed by an application using ImageMagick. The highest threat from...

JLSEC-2026-962 ImageMagick has heap buffer overflow in YUV 4:2:2 decoder

A heap buffer overflow write vulnerability exists in ReadYUVImage coders/yuv.c when processing malicious YUV 4:2:2 NoInterlace images. The pixel-pair loop writes one pixel beyond the allocated row buffer. ================================================================= ==204642==ERROR:...

JLSEC-2026-852

In IntensityCompare of /magick/quantize.c, there are calls to PixelPacketIntensity which could return overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the patch introduces and uses the ConstrainPixelIntensity function, which forces the pixel...

JLSEC-2026-1011 ImageMagick: Policy Bypass in MNG coder could

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, because of a missing check in the MNG coder it would be possible to read more images than the list limit policy would allow resulting in excessive resource use...

JLSEC-2026-1069 ImageMagick before 7.1.2-26 (and 6.x before 6.9.13-51) contains a memory leak in the TIFF encoder...

ImageMagick before 7.1.2-26 and 6.x before 6.9.13-51 contains a memory leak in the TIFF encoder that occurs when a temporary file cannot be created, resulting in a small memory leak...

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

Summary Magick fails to check for circular references between two MSLs, leading to a stack overflow. Details After reading a.msl using magick, the following is displayed: MSLStartElement - ReadImage - ReadMSLImage - ProcessMSLScript - xmlParseChunk - xmlParseTryOrFinish - MSLStartElement bash...

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-2026-850

A flaw was found in ImageMagick in MagickCore/quantum-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger a heap buffer overflow. This would most likely lead to an impact to application availability, but could potentially lead to an impact to data...

JLSEC-2026-1018 ImageMagick: Heap Buffer Over-Write in distributed pixel cache server

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, an attacker who can connect to a magick -distribute-cache service can cause a heap buffer over-write in the server process. This issue has been patched in...

JLSEC-2026-1022 ImageMagick has a Heap Buffer Underwrite in the Floyd-Steinberg depth dithering method

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-24, when using an image with mask the Floyd-Steinberg dithering method it will cause a negative heap buffer over-write. This issue has been patched in version 7.1.2-24...

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the TIFF encoder when memory allocation fails. Attackers can trigger allocation failures during TIFF image processing to cause memory exhaustion and denial of service...

JLSEC-2026-849

A flaw was found in ImageMagick in MagickCore/quantum-export.c. 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 long long as well as a shift exponent that is too large for 64-bit type...

JLSEC-2026-893

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...
