Vulnerability identifier: #VU133102

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-49218

CWE-ID: CWE-20

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 improper input validation in the DCM decoder when parsing crafted DCM images. A remote attacker can supply a specially crafted DCM image to cause a denial of service.

The issue can produce an image with invalid dimensions, which may lead to crashes in subsequent operations.
