View CSAF Summary Successful exploitation of this vulnerability could allow an attacker to cause the application to crash if a maliciously crafted DICOM file is opened. The following versions of Medixant RadiAnt DICOM are affected: RadiAnt DICOM <=2025.2 CVSS Vendor Equipment Vulnerabilities v3 4.3 Medixant Medixant RadiAnt DICOM Out-of-bounds Write Background Critical Infrastructure Sectors: Healthcare and Public Health Countries/Areas Deployed: Worldwide Company Headquarters Location: Poland Vulnerabilities Expand All + CVE-2026-17264 Opening a crafted DICOM file containing malicious JPEG-compressed pixel data triggers an attacker-controlled heap out-of-bounds write, which may allow an attacker to remotely execute arbitrary code. View CVE Details Affected Products Medixant RadiAnt DICOM Vendor: Medixant Product Version: Medixant RadiAnt DICOM: <=2025.2 Product Status: known_affected Remediations Mitigation Users should update to version 2026.1. It is also recommended to open DICOM files only from trusted and reliable sources. Additionally, the application is compiled with exploit mitigation mechanisms enabled, including Control Flow Guard (CFG), Data Execution Prevention (DEP), and Address Space Layout Randomization (ASLR), which significantly reduces the practical exploitability of the issue. https://www.radiantviewer.com/files/RadiAnt-2026.1-Setup.exe Relevant CWE: CWE-787 Out-of-bounds Write Metrics CVSS Version Base Score Base Severity Vector String 3.1 4.3 MEDIUM CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L 4.0 5.3 MEDIUM CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N Acknowledgments banda, oriotie, ax123, jihyeon4725, lacroix, and minzu reported this vulnerability to CISA Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy).
