CVE-2024-39880

Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. If a target visits a malicious page or opens a malicious file an attacker can leverage this vulnerability to execute code in the context of the current process.
