Code execution via unbounded S3M parsing
Published Aug 20, 2025 · Updated May 26, 2026
Stack-based buffer overflow in MJM Software QuickPlayer 2010 allows context-dependent attackers to execute code via a crafted S3M file. The S3M file parser fails to bound attacker-controlled file data before copying it into a stack buffer, permitting memory and control-flow overwrite. Exploitation requires a user to open the crafted file; the published ROP payload bypasses DEP and ASLR and executes code in the player's process.
