New in NSS 3.18.1

No new functionality is introduced in this release. This is a patch release to update the list of root CA certificates.

Notable Changes in NSS 3.18.1

  • The following CA certificate had the Websites and Code Signing trust bits restored to their original state to allow more time to develop a better transition strategy for affected sites. The Websites and Code Signing trust bits were turned off in NSS 3.18. But when Firefox 38 went into Beta, there was a huge spike in the number of certificate verification errors attributed to this change. So, to give website administrators more time to update their web servers, we reverted the trust bits back to being enabled.
    • OU = Equifax Secure Certificate Authority
      • SHA1 Fingerprint: D2:32:09:AD:23:D3:14:23:21:74:E4:0D:7F:9D:62:13:97:86:63:3A
  • The following CA certificate was removed after discussion about it in the mozilla.dev.security.policy forum.
    • CN = e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi
      • SHA1 Fingerprint: DD:E1:D2:A9:01:80:2E:1D:87:5E:84:B3:80:7E:4B:B1:FD:99:41:34
  • The following intermediate CA certificate has been added as actively distrusted because it was misused to issue certificates for domain names the holder did not own or control.
      • SHA1 Fingerprint: E1:F3:59:1E:76:98:65:C4:E4:47:AC:C3:7E:AF:C9:E2:BF:E4:C5:76
  • The version number of the updated root CA list has been set to 2.4

NSS 3.18.1 shared libraries are backward compatible with all older NSS 3.18 shared libraries. A program linked with older NSS 3.18 shared libraries will work with NSS 3.18.1 shared libraries without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs to the functions listed in NSS Public Functions will remain compatible with future versions of the NSS shared libraries.
