0 CVE-2025-12840 is a high-severity heap-based buffer overflow vulnerability in the Academy Software Foundation's OpenEXR library version 3.4.0. The flaw arises from improper validation of user-supplied data length during EXR file parsing, allowing remote attackers to execute arbitrary code if a user opens a malicious file or visits a malicious page. Exploitation requires user interaction but no privileges or authentication. The vulnerability impacts confidentiality, integrity, and availability, with a CVSS score of 7.8. There are no known exploits in the wild yet, and no patches have been released at the time of reporting. European organizations using OpenEXR in media, visual effects, or related industries face risks of remote code execution and potential system compromise. Mitigation involves restricting untrusted EXR file sources, monitoring for suspicious file activity, and applying vendor patches once available.
