Integer overflow in ImageMagick - CVE-2026-62946

Vulnerability identifier: #VU137768

CSH Severity: High

CVSS v4: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-62946

CWE-ID: CWE-190

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service or execute arbitrary code.

The vulnerability exists due to integer overflow in the JNX decoder when parsing an extremely large JNX file on 32-bit builds. A remote attacker can supply a specially crafted JNX file to cause a denial of service or execute arbitrary code.

Only 32-bit builds are vulnerable.
