How the CVE Works
The vulnerability exists in the CADImage plugin of IrfanView when parsing Computer Graphics Metafile (CGM) files. Due to insufficient bounds checking during file processing, an attacker can craft a malicious CGM file with specially designed data structures that trigger an out-of-bounds read when loaded. This occurs when the plugin fails to validate the length of user-controlled data before copying it into a fixed-size buffer. By carefully manipulating file contents, an attacker can overwrite adjacent memory regions, potentially leading to remote code execution within the context of the IrfanView process. The exploit requires user interaction (opening the malicious file) but can bypass standard mitigations due to the plugin’s flawed parsing logic.
