DescriptionThe vulnerability allows a remote attacker to bypass certificate validation checks.
The vulnerability exists due to presence of the TrustCor certificate in the Root Certificates list. the certificate is removed due to TrustCor's ownership also operated a business that produced spyware. Therefore, any checks that rely on digital signatures of trusted certificates were compromised.
Install updates from vendor's repository.
