Details

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 machine-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 machine-in-the-middle attacks,
this flaw could be exploited to eavesdrop on encrypted communications
from Ruby applications using these protocols. (CVE-2007-5770)
