Title: Browser Certificates
Additional information from the CERT/CC
Sun Microsystems has revoked the certificates with the following serial numbers:
You can confirm the revocation of these certificates at https://digitalid.verisign.com/services/server/search.htm.
Users who accept these certificates into their browser may inadvertently run malicious code signed by the compromised certificates. Any such code would appear to be from Sun Microsystems, thus creating a misleading sense of trust.
Sun Microsystems has provided identification information for the compromised certificates as well as instructions on how to remove them from common browsers. Users should follow Sun's instructions to remove these certificates from their browser and to prevent possible future addition.
The CERT Coordination Center thanks Sun Microsystems for bringing this issue to our attention.
