nss: Side channel vulnerabilities during RSA key generation

A flaw was found in NSS, where it is vulnerable to RSA key generation cache timing side-channel attacks. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. The highest threat to this flaw is to confidentiality...

nss: P-384 and P-521 implementation uses a side-channel vulnerable modular inversion function

A side-channel flaw was found in NSS, in the way P-384 and P-521 curves are used in the generation of EDSA signatures, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. The highest threat from this...
