Magick.NET Q16 AnyCPU: ImageMagick: Policy Bypass in DCM decoder could result in image with invalid dimensions (CVE-2026-49218)
A vulnerability in the ImageMagick DCM decoder allows bypassing a policy check, resulting in images with invalid dimensions. This flaw can cause crashes in subsequent image processing operations. The issue affects Magick.NET-Q16-AnyCPU versions prior to 14.14.0. No known exploits are reported in the wild. The vulnerability is classified as high severity due to its potential to cause denial of service via application crashes.
AI Analysis
Technical Summary
CVE-2026-49218 is a vulnerability in the ImageMagick DCM decoder where a missing validation check permits creation of images with invalid dimensions. This can lead to crashes in other operations that process these malformed images. The vulnerability is tracked as CWE-20 (Improper Input Validation) and affects Magick.NET-Q16-AnyCPU versions before 14.14.0. There is no indication of confidentiality or integrity impact, but the availability impact is high due to potential crashes. No patch or official fix information is provided in the data.
Potential Impact
The vulnerability can cause denial of service by crashing processes that handle images with invalid dimensions generated by the flawed DCM decoder. There is no reported impact on confidentiality or integrity. No known exploits have been observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted DCM images or implement additional input validation to detect invalid image dimensions before processing.
