CVE-2026-28691 [HIGH] ImageMagick vulnerabilities
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)
It was discovered that ImageMagick incorrectly handled certain DJVU
images. An attacker could possibly use this issue to trigger a heap
buffer over-read, resulting in information disclosure. (CVE-2026-27799)
It was discovered that ImageMagick incorrectly handled certain MNG
images. An attacker could possibly use this issue to trigger a stack

ImageMagick: ImageMagick: Information disclosure via heap buffer over-read when processing images
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 occurs when processing an image with small dimension using the `-wavelet-denoise` operator. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
A flaw was found in ImageMagick. A local user could exploit a heap buffer over-read vulnerability by processing a specially crafted image with small dimensions using the `-wavelet-denoise` operator. This vulnerability may lead to the disclosure of sensitive information.
Statement: This MODERATE impact vulnerability in ImageMagick affects Red Hat Enterprise Linux. A heap buffer ove
