How the CVE Works
CVE-2025-7268 is a critical vulnerability in IrfanView’s CADImage Plugin, specifically in its handling of DXF files. The flaw arises due to insufficient bounds checking during DXF file parsing, leading to an out-of-bounds read. Attackers can craft a malicious DXF file that, when opened, triggers a read operation beyond the allocated buffer. This can corrupt memory and allow 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 vulnerability stems from improper validation of user-supplied data, enabling remote attackers to exploit the lack of boundary checks.
