Description

Mozilla browsers contain a flaw that may allow a denial of service on stored certificates. The issue is triggered when receiving certificates with existing DN and different serial number as a built-in CA root cert occurs, and will result in the built-in CA root cert being overwritten. Ultimately this may result in loss of availability for sites using the original built-in CA root cert.

Classification

Location: Remote / Network Access
Attack Type: Authentication Management, Denial of Service
Impact: Loss of Availability
Solution: Workaround, Patch / RCS
Exploit: Exploit Public
Disclosure: Vendor Verified
OSVDB: Web Related

Solution

Mozilla has released a patch to address this vulnerability. Additionally, it is possible to temporarily work around the flaw by implementing the following workaround: check the certificate store and remove untrusted certificates if noticing the error -8182 which is "Peer's certificate has an invalid signature." It may be necessary to obtain and manually install the correct CA root certificates again.
