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. (CVE-2007-5162)
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. (CVE-2007-5770)
