Hi, I am currently hunting a SSL problem between iOS 5 devices (iphone, ipod, ipad) and openssl/libssl 0.9.8.
We are running a dovecot IMAP server under Ubuntu 10.04, offering SSL-encrypted IMAP. Works stable with all software and devices except Apple mobile devices with iOS 5. Analyzing network traffic with Wireshark shows openssl complaining and aborting the connection: -> TLSv1 Client Hello <- TLSv1 Server Hello, Certificate, Server Hello Done -> TLSv1 Client Key Exchange -> TLSv1 Change Cipher Spec, Encrypted Handshake Message <- TLSv1 Alert (Level: Fatal, Description: Bad Record MAC) This smells rather like a bug in iOS, especially since it occurs since upgrading to iOS 5 and with iOS only, all other clients do work. Allegedly Apple „fixed” something about SSL in the iOS5 upgrade and moved to a newer protocol version. However, this could nevertheless be a problem in openssl. Have you heard about that problem before? regards Hadmut ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [email protected] Automated List Manager [email protected]
