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-2026-841

In WriteOnePNGImage of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory and memset allows for an out-of-bounds write later when PopShortPixel from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply ...

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:...

ImageMagick is a free and open-source software suite, used for editing and manipulating digital images. The AppImage version ImageMagick might use an empty path when setting MAGICKCONFIGUREPATH and LDLIBRARYPATH environment variables while executing, which might lead to arbitrary code execution b...

JLSEC-2026-885

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

JLSEC-2026-888

A flaw was found in ImageMagick in versions before 7.0.11. A potential cipher leak when the calculate signatures in TransformSignature is possible. The highest threat from this vulnerability is to data confidentiality...

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...

JLSEC-2026-993

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when Magick parses an XML file it is possible that a single zero byte is written out of the bounds. This issue has been fixed in versions 6.9.13-44 and 7.1.2-1...

JLSEC-2026-976 ImageMagick has heap use-after-free in the MSL encoder

A heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed. SUMMARY: AddressSanitizer: heap-use-after-free MagickCore/image.c:1195 in DestroyImage Shadow bytes around t...

JLSEC-2026-882

A flaw was found in ImageMagick in coders/webp.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-2026-1005

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-21 and 6.9.13-46, a malicious MIFF file could trigger an overflow when a user opens it in the display tool and right-clicks a tile to invoke the Load / Update menu item. This vulnerabilit...

JLSEC-2026-952 ImageMagick: Policy bypass through path traversal allows reading restricted content despite secured policy

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, ImageMagick’s path security policy is enforced on the raw filename string before the filesystem resolves it. As a result, a policy rule such as /etc/ can be...

JLSEC-2026-877

A divide-by-zero flaw was found in ImageMagick 6.9.11-57 and 7.0.10-57 in gem.c. This flaw allows an attacker who submits a crafted file that is processed by ImageMagick to trigger undefined behavior through a division by zero. The highest threat from this vulnerability is to system availability...

JLSEC-2026-902

A heap-based buffer overflow issue was discovered in ImageMagick's ImportMultiSpectralQuantum function in MagickCore/quantum-import.c.
