How the CVE Works
The vulnerability (CVE-2025-7269) exists in IrfanView’s CADImage Plugin when parsing DXF files. Due to insufficient bounds checking, an attacker can craft a malicious DXF file that triggers an out-of-bounds read when processed. This occurs because the plugin fails to validate the length of user-supplied data, allowing memory corruption. By exploiting this flaw, an attacker can manipulate the read operation to leak sensitive data or execute arbitrary code within the context of the application. User interaction is required (e.g., opening a malicious file), making social engineering a likely attack vector. The vulnerability was reported under ZDI-CAN-26188 and carries a critical CVSS 4.0 rating.
