OpenSSL 1.0.1d + AES-NI

After today's OpenSSL update I was a bit surprised when alpine stopped working and random characters were appearing in the dialogue when I tested IMAP manually with OpenSSL's s_client. Interestingly it affected only one of my machines.

Apparently there's a regression in the current OpenSSL 1.0.1d that corrupts the data
stream on CPUs with AES-NI, see and follow-ups.

If you've got a CPU with AES-NI (i5, i7, ...) consider rebuilding the 1.0.1d package with the patch from;h=32cc247 before upgrading. In my case the patch solved the problem.

Thank you Cesare!

I had the same exact problem with irssi when connecting securely since my CPU does have AES-NI:
/connect -ssl_verify -ssl_capath /etc/ssl/certs 7070 # this generated similar random characters you speak of
# whereas:
/connect 6667 # did not generate said random characters and worked fine
Hopefully openssl gets rebuilt soon by the Slackware team.
