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 the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Title: ImageMagick vulnerabilities
Summary: Several security issues were fixed in ImageMagick.
It was discovered that ImageMagick incorrectly handled certain images
when using the wavelet-denoise operator. An attacker could possibly use
this issue to trigger a heap buffer over-read, resulting in information
disclosure. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,
Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2026-27798)
