Red Hat has issued an update for stunnel. This fixes a vulnerability allowing malicious people to cause a Denial of Service.
The vulnerability is caused due to a race condition. The "SIGCHLD" signal handler isn't blocked, which potentially may result in the client counter loosing count. This could possible be exploited to cause a Denial of Service.
This only affects configurations where stunnel spawns a new child process for each connection.
