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) It was discovered that ImageMagick incorrectly handled certain JBIG images. An attacker could possibly use this issue to trigger a pointer dereference error, resulting in a denial of service. (CVE-2026-28691) It was discovered that ImageMagick incorrectly handled certain MAT images. An attacker could possibly use this issue to trigger a heap buffer over-read, resulting in information disclosure. (CVE-2026-28692) It was discovered that ImageMagick incorrectly handled certain DIB images. An attacker could possibly use this issue to trigger an integer overflow, resulting in arbitrary code execution.
