Stack-based buffer overflow in ImageMagick - CVE-2026-42050

Vulnerability identifier: #VU127726

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-42050

CWE-ID: CWE-121

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to stack-based buffer overflow in XTileImage when processing a malicious MIFF file in the display tool after a tile is right-clicked to invoke the Load / Update menu item. A remote attacker can trick the victim into opening a crafted MIFF file to cause a denial of service.

User interaction is required to open the crafted file and invoke the menu item.
