Ubuntu Security Notice 596-1 - Chris Clark discovered that Ruby's HTTPS module did not check for commonName mismatches early enough during SSL negotiation. If a remote attacker were able to perform man-in-the-middle attacks, this flaw could be exploited to view sensitive information in HTTPS requests coming from Ruby applications. It was discovered that Ruby's FTPTLS, telnets, and IMAPS modules did not check the commonName when performing SSL certificate checks. If a remote attacker were able to perform man-in-the-middle attacks, this flaw could be exploited to eavesdrop on encrypted communications from Ruby applications using these protocols.

It was discovered that the Ruby HTTP(S) module performs insufficient validation of SSL certificates, which may lead to man-in-the-middle attacks. It was discovered that the Ruby modules for FTP, Telnet, IMAP, POP and SMTP perform insufficient validation of SSL certificates, which may lead to man-in-the-middle attacks.
