How the CVE Works
The vulnerability in IrfanView’s CADImage Plugin arises during the parsing of Computer Graphics Metafile (CGM) files. Due to insufficient bounds checking, the plugin fails to validate the length of user-supplied data when processing CGM files. This allows an attacker to craft a malicious CGM file that triggers an out-of-bounds read when loaded. By exploiting this flaw, an attacker can corrupt memory and gain remote code execution within the context of the application. User interaction is required, such as opening a malicious file or visiting a compromised webpage hosting the exploit.
