The SuSE Linux distributions 7.2 and 7.3 as well as SLES7 have
stunnel-3.14 (unpatched). It does have protocol-dependent code, but there
are no format string bugs that are exploitable (only "unclean" lines like
fdprintf(local, "220 Go ahead", line); ).

You have to dig into it for a few minutes. The version statement does not
hold.
