Description Tomas Hoger 2007-10-01 11:40:35 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2007-5162 to the following vulnerability:

The connect method in lib/net/http.rb in the (1) Net::HTTP and (2) Net::HTTPS
libraries in Ruby 1.8.5 and 1.8.6 does not verify that the commonName (CN)
field in a server certificate matches the domain name in an HTTPS request,
which makes it easier for remote attackers to intercept SSL transmissions via a
man-in-the-middle attack or spoofed web site.

Comment 2 Tomas Hoger 2007-10-01 13:24:36 UTC 
This issue does not affect ruby packages as shipped in Red Hat Enterprise Linux
2.1 and 3, as they do not provide SSL support for Net::HTTP class.
