Kerentanan Observable Discrepancy pada mozilla firefox, fedoraproject fedora +2 lainnya. Skor CVSS 3.1 4.4 (Medium) menurut NVD.

Deskripsi (NVD)

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78.
