Details
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
buffer overflow, resulting in arbitrary code execution. (CVE-2026-28690)
