### Impact s2n-tls uses the Linux atexit function to register functions that clean up the global state when the process exits. In multi-threaded environments, the atexit handler may clean up state which is still in use by other threads. When this occurs, the exiting process may experience a segmentation fault or other undefined behavior. Customers of AWS services do not need to take action. Applications using s2n-tls should upgrade to the most recent release of s2n-tls. **Impacted versions**: < v1.5.9. ### Patches The patch commit [493b771](https://github.com/aws/s2n-tls/commit/493b77167dc367c394de23cfe78a029298e2a254) is included in s2n-tls v1.5.9 [1] ### Workarounds The atexit handler may be disabled by calling `s2n_disable_atexit()` prior to initializing s2n-tls. The atexit handler is off by default in the patched versions.
