  • requires NSS 3.25

  • Mozilla Firefox 48.0.2:

    • Mitigate a startup crash issue caused on Windows (bmo#1291738)

  mozilla-nss was updated to NSS 3.25. New functionality:

  • Implemented DHE key agreement for TLS 1.3
  • Added support for ChaCha with TLS 1.3
  • Added support for TLS 1.2 ciphersuites that use SHA384 as the PRF
  • In previous versions, when using client authentication with TLS
    1.2, NSS only supported certificate_verify messages that used the same
    signature hash algorithm as used by the PRF. This limitation has been
    removed.
  • Several functions have been added to the public API of the NSS
    Cryptoki Framework. New functions:
  • NSSCKFWSlot_GetSlotID
  • NSSCKFWSession_GetFWSlot
  • NSSCKFWInstance_DestroySessionHandle
  • NSSCKFWInstance_FindSessionHandle Notable changes:
  • An SSL socket can no longer be configured to allow both TLS 1.3 and
    SSLv3
  • Regression fix: NSS no longer reports a failure if an application
    attempts to disable the SSLv2 protocol.
  • The list of trusted CA certificates has been updated to version 2.8
  • The following CA certificate was Removed Sonera Class1 CA
  • The following CA certificates were Added Hellenic Academic and
