CVE-2013-4073
CVSS v2.0
6.8
Média
| Vetor | AV:N/AC:M/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Ruby versions 1.8 before 1.8.7-p374
Ruby versions 1.9 before 1.9.3-p448
Ruby versions 2.0 before 2.0.0-p247
Description
The issue allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. This occurs because the OpenSSL::SSL.verify certificate identity function does not properly handle a '0' character in a domain name in the Subject Alternative Name field of an X.509 certificate.
Recommendations
For Ruby 1.8, update to version 1.8.7-p374 or later.
For Ruby 1.9, update to version 1.9.3-p448 or later.
For Ruby 2.0, update to version 2.0.0-p247 or later.
