How the CVE Works
CVE-2025-7266 is a memory corruption vulnerability in IrfanView’s CADImage Plugin when parsing DXF files. The flaw arises due to insufficient validation of user-supplied data, leading to improper memory handling. Attackers can craft a malicious DXF file that, when opened, triggers memory corruption, allowing remote code execution (RCE) within the context of the application. Exploitation requires user interaction (e.g., opening a malicious file). The vulnerability was reported under ZDI-CAN-26174 and carries a critical CVSS 4.0 rating due to its potential for arbitrary code execution.
