Summary
nss vulnerabilities
Details

Keegan Ryan discovered that NSS incorrectly handled ECDSA key generation. A local attacker could possibly use this issue to perform a cache-timing attack and recover private ECDSA keys. (CVE-2018-0495)

It was discovered that NSS incorrectly handled certain v2-compatible ClientHello messages. A remote attacker could possibly use this issue to perform a replay attack. (CVE-2018-12384)

It was discovered that NSS incorrectly handled certain padding oracles. A remote attacker could possibly use this issue to perform a variant of the Bleichenbacher attack. (CVE-2018-12404)
