ImageMagick before 7.1.2-27 contains a memory leak vulnerability in the magick command-line interface when invalid options are provided. Attackers can trigger memory exhaustion by repeatedly supplying malformed command-line arguments to consume system resources...
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-2026-1041 ImageMagick: Policy Bypass in concatenate operation due to missing checks
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-26he, the -concatenate operation is missing policy checks, potentially resulting in both reading and writing to paths disallowed by the security policy. This issue has been...
JLSEC-2026-922 ImageMagick has Undefined Behavior (function-type-mismatch) in CloneSplayTree
Summary - Target: ImageMagick commit ecc9a5eb456747374bae8e07038ba10b3d8821b3 - Type: Undefined Behavior function-type-mismatch in splay tree cloning callback - Impact: Deterministic abort under UBSan DoS in sanitizer builds. No crash in a non-sanitized build; likely low security impact. - Trigge...
JLSEC-2026-1025 ImageMagick has a Heap Buffer Over-Write in MAT decoder on 32-bit systems
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-24, a missing check of a return value could lead to a heap buffer over-write in the MAT decoder on 32-bit systems. This issue has been patched in versions 6.9.13-48...
JLSEC-2026-968 ImageMagick: Heap overflow in pcd decoder leads to out of bounds read.
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 lacks proper boundary checking when processing Huffman-coded data from PCD Photo CD files. The decoder contains an function that has an incorrect...
JLSEC-2026-1059 ImageMagick before 7.1.2-15 (and 6.x before 6.9.13-40) contains a heap out-of-bounds read in the...
ImageMagick before 7.1.2-15 and 6.x before 6.9.13-40 contains a heap out-of-bounds read in the PCD coder's DecodeImage loop. A crafted PCD file can trigger a one-byte heap out-of-bounds read during image decoding, resulting in denial of service and potential disclosure of an adjacent heap byte...
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-2026-862
In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator where a sizet cast should have been a ssizet cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick. Red Hat Product Security marked this as Low severity...
JLSEC-2026-1014 ImageMagick: Infinite Loop in the MIFF decoder can lead to CPU exhaustion
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2.23 and 6.9.13-48, due to a missing check in the MIFF decoder, a crafted file could cause an infinite loop resulting in CPU exhaustion.

JLSEC-2026-984 ImageMagick has heap-based buffer overflow in UHDR encoder
A heap-based buffer overflow in the UHDR encoder can happen due to truncation of a value and it would allow an out of bounds write. ================================================================ ==2158399==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x521000039500 at pc...
JLSEC-2026-951 ImageMagick has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer
The UIL and XPM image encoder do not validate the pixel index value returned by GetPixelIndex before using it as an array subscript. In HDRI builds, Quantum is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger ...
