CVE-ID: CVE-2007-4680

Available for: Windows XP or Vista

Impact: A remote attacker may be able to cause an untrusted certificate to appear trusted

Description: An issue exists in the validation of certificates. A man-in-the-middle attacker may be able to direct the user to a legitimate site with a valid SSL certificate, then re-direct the user to a spoofed web site that incorrectly appears to be trusted. This could allow user credentials or other information to be collected. This update addresses the issue through improved validation of certificates. This issue is addressed for Mac OS X in Security Update 2007-008, and is incorporated into Mac OS X v10.4.11 and Mac OS X v10.5 or later.
