Summary

Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES
ciphers were vulnerable to birthday attacks. A remote attacker could
possibly use this flaw to obtain clear text data from long encrypted
sessions. This update causes NSS to limit use of the same symmetric key.
(CVE-2016-2183)

It was discovered that NSS incorrectly handled Base64 decoding. A remote
attacker could use this flaw to cause NSS to crash, resulting in a denial
of service, or possibly execute arbitrary code. (CVE-2017-5461)

the latest CA certificate bundle.
