"All versions of stunnel from 3.15 to 3.21c are vulnerable to format
string bugs in the functions which implement smtp, pop, and nntp
client negotiations. Using stunnel with the '-n service' option and
the '-c' client mode option, a malicious server could use the format
sting vulnerability to run arbitrary code as the owner of the current
stunnel process. Version 3.22 is not vulnerable to this bug."
