CVE-2018-12384

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.

Firefox 60 is now the only supported version of the ESR series and it brings a completely new browser engine, designed to take full advantage of the processing power in modern devices. Firefox also now exclusively supports extensions built using the WebExtension API.

This update brings Firefox 60.2.1 along with the needed updated libraries :

• NSS 3.36.5 (fixes CVE CVE-2018-12384)
• Sqlite 3.22.0
• Hunspell 1.6.2

These are all security issues fixed in the libfreebl3-3.69.1-1.2 package on the GA media of openSUSE Tumbleweed.

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)
