I would like to report two bugs. I recently upgraded to stunnel 5.50 on
FreeBSD 12.0 and noticed that the stunnel server service now crashes
periodically. When checking the logs after a crash, I see the following
error:
INTERNAL ERROR: Dead canary at
/usr/src/crypto/openssl/ssl/statem/extensions_sr
INTERNAL ERROR: Double free attempt: ptr=0x802119050
alloc=/usr/src/crypto/openssl/crypto/stack/stack.c:198
free#1=/usr/src/crypto/openssl/crypto/stack/stack.c:376
free#2=/usr/src/crypto/openssl/ssl/ssl_sess.c:814
Hello,
Thank you for reporting bugs, I'm trying to replicate them.
Is stunnel installed from sources or packages? What about openssl, is it
installed from sources or packages?
Could you send
stunnel -version.
Best regards,
Małgorzata Olszówka
