Vulnerability Name:

CVE-2011-3422 (CCN-69556)

Assigned:2011-09-02
Published:2011-09-02
Updated:2017-08-29
Summary: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.
