The OpenSSL::SSL.verify_certificate_identity function in
lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374,
1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247
does not properly handle a ‘\0’ character in a domain name in
the Subject Alternative Name field of an X.509 certificate, which
allows man-in-the-middle attackers to spoof arbitrary SSL servers
via a crafted certificate issued by a legitimate Certification
Authority, a related issue to CVE-2009-2408.
