CVE-2020-37050Public exploit

Code execution via Unicode playlist SEH overwrite

Published Jan 30, 2026 · Updated Jan 30, 2026

Buffer overflow in Quick Player 1.3 allows context-dependent attackers to execute arbitrary code by supplying a crafted .m3l playlist file. The playlist loader copies an oversized Unicode payload into a fixed stack buffer, overwriting an SEH return path and redirecting execution to embedded shellcode. Exploitation requires a user to open the file through the PL, File, and Load List workflow; successful code runs with the application's privileges.
