CVE-2011-3422 Information

Description

The Keychain implementation in Apple Mac OS X 10.6.8 and earlier does not properly handle an untrusted attribute of a Certification Authority certificate which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via an Extended Validation certificate as demonstrated by https access with Safari.
