CVE-2023-37734Public exploit

Code execution via oversized M3U playlist entry

Published Aug 10, 2023 · Updated Oct 9, 2024

Buffer overflow in EZ softmagic MP3 Audio Converter 2.7.3.700 allows context-dependent attackers to execute code via a crafted M3U playlist. Its playlist loader copies an overlong M3U entry into a fixed-size buffer without checking its length, allowing control-flow overwrite. An attacker must induce a user to load the crafted playlist on Windows; the demonstrated payload runs with the application's privileges.
