Magick.NET Q16 AnyCPU: ImageMagick has a Heap Buffer Over-Write in MAT decoder on 32-bit systems (CVE-2026-48994)
A heap buffer over-write vulnerability exists in the MAT decoder of ImageMagick on 32-bit systems due to a missing check of a return value. This flaw affects Magick.NET-Q16-AnyCPU versions prior to 14.14.0. The vulnerability does not impact confidentiality or integrity but can cause availability issues by crashing the application or causing denial of service. No known exploits are reported in the wild. The vulnerability is classified as CWE-122 (Heap-based Buffer Overflow).
AI Analysis
Technical Summary
CVE-2026-48994 describes a heap buffer over-write vulnerability in the MAT image decoder component of ImageMagick when running on 32-bit systems. The root cause is a missing validation of a return value, which can lead to memory corruption. This issue affects Magick.NET-Q16-AnyCPU versions before 14.14.0. The vulnerability has a CVSS 3.1 vector indicating network attack complexity is high, no privileges or user interaction required, and impacts availability only. There is no vendor advisory or patch information provided, and no known exploits have been reported.
Potential Impact
The vulnerability can cause a denial of service by crashing the application processing MAT images on affected 32-bit systems. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid processing untrusted MAT images on 32-bit systems using affected versions of Magick.NET-Q16-AnyCPU.
