CVE-2026-61870

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the VIFF encoder when memory allocation fails. Attackers can trigger allocation failures by processing specially crafted VIFF images to exhaust available memory and cause denial of service.

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the VIFF encoder when memory allocation fails. Attackers can trigger allocation failures by processing specially crafted VIFF images to exhaust available memory and cause denial of service.

When an allocation fails in the VIFF encoder a memory leak will occus.

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the VIFF encoder when memory allocation fails. Attackers can trigger allocation failures by processing specially crafted VIFF images to exhaust available memory and cause denial of service.

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 before 7.1.2-18 contains a memory leak vulnerability in the META reader when processing APP1JPEG input paths. Attackers can trigger this memory leak by providing specially crafted APP1JPEG image files, causing denial of service through resource exhaustion.(CVE-2026-56366)

ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the magnify operation that allows attackers to read out of bounds memory. An unrecognized magnify:method value triggers an out of bounds read, potentially exposing sensitive information or causing denial of service.(CVE-2026-56372)

ImageMagick before 7.1.2-15 contains a use-after-free vulnerability in the PDB decoder that uses a stale pointer when memory allocation fails. Attackers can trigger this vulnerability by processing malicious PDB files to cause crashes or write a single zero byte to freed memory.(CVE-2026-56373)

ImageMagick before 7.1.2-26 and 6.9.13-51 is missing a check for the allowed memory allocation limit in matrix-backed operations such as -canny. An attacker can supply a crafted image that causes ImageMagick to allocate more memory than permitted by the configured policy, resulting in a denial of service.(CVE-2026-61465)

ImageMagick before 7.1.2-26 contains a heap use-after-free vulnerability caused by missing null check when parsing XMP profiles. Attackers can craft malicious image files with specially crafted XMP data to trigger the vulnerability and cause application crashes.(CVE-2026-61857)

ImageMagick before 7.1.2-26 contains a policy bypass vulnerability in the APNG encoder and external delegates due to missing validation checks. Attackers can write files to disallowed paths by bypassing configured policy restrictions through the APNG encoding process.(CVE-2026-61858)

ImageMagick before 7.1.2-26 contains a use-after-free vulnerability in the FormatMagickCaption method when memory allocation fails. Attackers can trigger memory allocation failures to cause a dangling pointer to reference freed memory, potentially enabling denial of service or code execution.(CVE-2026-61861)
