Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. CREATE(Triage):(User=admin) [CVE-2020-6829|https://nvd.nist.gov/vuln/detail/CVE-2020-6829]
