How the CVE Works
The vulnerability in IrfanView’s CADImage Plugin arises during the parsing of DXF files due to insufficient validation of user-supplied data. Attackers craft malicious DXF files, triggering memory corruption when processed. This corruption allows arbitrary code execution within the context of the application. Exploitation requires user interaction, such as opening a malicious file or visiting a compromised webpage. The flaw stems from improper bounds checking, leading to heap or stack-based overflows. Successful exploitation grants attackers the same privileges as the targeted process, enabling system compromise.
