Dear Users,
Please test the new stunnel 4.21 and report your issues on the Bug Tracking System (http://stunnel.mirt.net/bts.html) or email the information to the stunnel-users mailing list. This is the easiest way to help stunnel working fine on your various systems. I was developing it for quite a long time and I likely failed to fix all the bugs. I'm especially interested in all compilation or runtime issues with the new FIPS and libwrap code.
By the time you can find a patch for setuid/setgid+chroot problem here: ftp://stunnel.mirt.net/stunnel/setuid.patch
Best regards, Mike
