| CVE-2018-12404 | Med | 0.42 | 5.9 | 0.44 | May 2, 2019 | A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) and affects all NSS versions prior to NSS 3.41. | ||
| CVE-2016-1938 | Med | 0.42 | 6.5 | 0.03 | Jan 31, 2016 | The s_mp_div function in lib/freebl/mpi/mpi.c in Mozilla Network Security Services (NSS) before 3.21, as used in Mozilla Firefox before 44.0, improperly divides numbers, which might make it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging… | ||
| CVE-2018-12384 | Med | 0.38 | 5.9 | 0.01 | Apr 29, 2019 | When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS… | ||
| CVE-2016-9574 | Med | 0.38 | 5.9 | 0.01 | Jul 19, 2018 | nss before version 3.30 is vulnerable to a remote denial of service during the session handshake when using SessionTicket extension and ECDHE-ECDSA. | ||
