Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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).
Update the affected packages.
