Heap-based buffer overflow in ImageMagick - CVE-2026-31853

Vulnerability identifier: #VU123890

CSH Severity: Medium

CVSS v4: 8.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-31853

CWE-ID: CWE-122

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error on 32-bit systems in SFW decoder. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
