CVE-2020-37065Public exploit

Code execution via oversized SongPattern input

Published Feb 3, 2026 · Updated Feb 3, 2026

Buffer overflow in StreamRipper32 2.6 allows attackers to execute arbitrary code by supplying an oversized SongPattern value. The Station/Song section copies more than 256 bytes of SongPattern input into memory without checking the input length, allowing the buffer to be overwritten. The crafted value must reach the Windows desktop application through active user interaction; successful memory corruption allows code execution in the application's process.
