CVE-2018-12384 is fixed in 2 products on 1 platform, first by libnss3 2:3.35-2ubuntu2.1, released December 11, 2018. It is not reported as exploited. Patch Radar priority: Routine.
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 1.3.
