What is CVE-2024-6812?

This vulnerability exists in IrfanView's handling of WSQ files, where a lack of adequate validation of user-supplied input allows for out-of-bounds writes. An attacker can exploit this vulnerability by crafting a malicious WSQ file or web link that, when accessed by a user, triggers the execution of arbitrary code in the context of the affected IrfanView installation. As user interaction is a prerequisite for this attack, it underscores the importance of cautious file handling and web browsing practices. Affected users are strongly advised to update to the latest version of IrfanView to mitigate the risk associated with this vulnerability.
