How the CVE Works
The vulnerability exists in the IrfanView CADImage Plugin when parsing Computer Graphics Metafile (CGM) files. Due to insufficient bounds checking, the plugin fails to validate the length of user-supplied data before processing it. This allows an attacker to craft a malicious CGM file that triggers an out-of-bounds read, corrupting memory. By carefully manipulating the file structure, an attacker can achieve remote code execution within the context of the application. Exploitation requires user interaction, such as opening a malicious file or visiting a compromised webpage hosting the exploit.
