MS KB2524375: Fraudulent Digital Certificates Could Allow Spoofing (deprecated)

Medium Nessus Plugin ID 52977


This plugin has been deprecated.


The remote host is missing KB2524375, which updates the system's SSL certificate blacklist.

A certificate authority (CA) has revoked a number of fraudulent SSL certificates for several prominent, public websites. Without this update, browsers will be unable to learn that the certificates have been revoked if either Online Certificate Status Protocol (OCSP) is disabled, or OCSP is enabled and fails.

If an attacker can trick someone into using the affected browser and visiting a malicious site using one of the fraudulent certificates, he may be able to fool that user into believing the site is a legitimate one. In turn, the user could send credentials to the malicious site or download and install applications.


Apply the relevant update provided by Microsoft.
