CVE-2026-25988

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, sometimes msl.c fails to update the stack index, so an image is stored in the wrong slot and never freed on error, causing leaks. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Use ImageMagick to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

Security Fix(es):

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 heap information disclosure vulnerability exists in ImageMagick's PSD (Adobe Photoshop) format handler. When processing a maliciously crafted PSD file containing ZIP-compressed layer data that decompresses to less than the expected size, uninitialized heap memory is leaked into the output image. Versions 7.1.2-15 and 6.9.13-40 contain a patch.(CVE-2026-24481)

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, Magick fails to check for multi-layer nested mvg conversions to svg, leading to DoS. Versions 7.1.2-15 and 6.9.13-40 contain a patch.(CVE-2026-24484)

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, when a PCD file does not contain a valid Sync marker, the DecodeImage() function becomes trapped in an infinite loop while searching for the Sync marker, causing the program to become unresponsive and continuously consume CPU resources, ultimately leading to system resource exhaustion and denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.(CVE-2026-24485)

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 heap buffer over-read vulnerability exists in multiple raw image format handles. The vulnerability occurs when processing images with -extract dimensions larger than -size dimensions, causing out-of-bounds memory reads from a heap-allocated buffer. Versions 7.1.2-15 and 6.9.13-40 contain a patch.(CVE-2026-25576)

ImageMagick is a widely used open-source software suite for editing and manipulating digital images. Prior to version 7.1.2-15, a memory leak exists in the ASHLAR image writer. An attacker can exploit this vulnerability by providing a specially crafted image file, which causes small memory objects to be allocated but never freed. Continuous processing of such malicious images will gradually exhaust the process memory, ultimately leading to a Denial of Service (DoS) condition. This vulnerability is classified under CWE-401 (Improper Release of Memory Before Removing Last Reference).(CVE-2026-25637)

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 memory leak vulnerability exists in coders/msl.c. The vulnerability stems from the WriteMSLImage function returning early without releasing allocated resources. A remote attacker could exploit this vulnerability by providing a specially crafted image file, leading to memory exhaustion and ultimately resulting in a Denial of Service (DoS) condition, rendering the system or application unavailable. This vulnerability is classified as CWE-401 (Memory Leak).(CVE-2026-25638)

ImageMagick is free and open-source software used for editing and manipulating digital images. The WriteUHDRImage function in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. Prior to version 7.1.2-15, when image dimensions are large, the multiplication overflows the 32-bit int, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out-of-bounds heap write, which could be exploited to cause a denial of service or, in some cases, arbitrary code execution.(CVE-2026-25794) …

ImageMagick is a widely used free and open-source software for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a NULL pointer dereference vulnerability exists in the ReadSFWImage() function located in coders/sfw.c. When temporary file creation fails, the read_info structure is destroyed before its filename member is accessed, causing the program to dereference a NULL pointer and crash. An attacker could exploit this issue to cause a Denial of Service (DoS).(CVE-2026-25795)

  • debian/patches/CVE-2026-25797_CVE-2026-25965_CVE-2026-25968_CVE-2026-25982.patch: Fix memory leaks, stack overflows, integer overflows and out‑of‑bounds reads; add bounds checks, validate DCM entry sizes, sanitize PostScript filenames, canonicalize paths and free resources; escape user-controlled strings written as raw HTML in the HTML coder; cause was unsafe header and filename parsing, incorrect assumptions about byte counts, path resolution, unnormalized path matching allowing policy bypass, and unescaped HTML output enabling cross-site scripting.
