Mozilla/Firefox certificate denial of service
| mozilla-certificate-dos (16706) |  Low Risk |
Description:
Mozilla and Firefox are vulnerable to a denial of service attack. A remote attacker could create a specially-crafted certificate with the same Distinguished Name (DN) as a built-in root Certificate Authority (CA) certificate and import the malicious certificate to the victim's certificate store, without the victim's knowledge. This prevents the victim from gaining access to a legitimate Secure Sockets Layer (SSL) Web site that contains a root CA with the same DN as the malicious root certificate in the victim's certificate store. An attacker could exploit this vulnerability by hosting the malicious certificate on a Web site or by sending it to a victim as an HTML email.
