AI-suggested
To mitigate CVE-2025-2634, European organizations should: 1) Immediately audit and inventory all LabVIEW installations and identify versions at or below 2025 Q1. 2) Restrict the opening of VI files from untrusted or unknown sources, implementing strict file handling policies and user training to recognize suspicious files. 3) Employ application whitelisting and sandboxing techniques to limit the execution context of LabVIEW and reduce the impact of potential exploitation. 4) Monitor and analyze network and endpoint logs for unusual activity related to LabVIEW processes, especially file open events and memory anomalies. 6) Incorporate this vulnerability into vulnerability management and incident response plans, preparing for rapid containment and remediation if exploitation is detected. 7) Educate users on the risks of opening unsolicited VI files and implement multi-factor authentication to reduce the risk of unauthorized access facilitating exploitation.
Description
Out of bounds read vulnerability due to improper bounds checking in NI LabVIEW in fontmgr may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted VI. This vulnerability affects NI LabVIEW 2025 Q1 and prior versions.
