Notable Changes in NSS 3.15.2

  • Bug 880543 - Support for AES-GCM ciphersuites that use the SHA-256 PRF

  • Bug 663313 - MD2, MD4, and MD5 signatures are no longer accepted for OCSP or CRLs, consistent with their handling for general certificate signatures.

  • Bug 884178 - Add PK11_CipherFinal macro

Bugs fixed in NSS 3.15.2

  • Bug 734007 - sizeof() used incorrectly

  • Bug 900971 - nssutil_ReadSecmodDB() leaks memory

  • Bug 681839 - Allow SSL_HandshakeNegotiatedExtension to be called before the handshake is finished.

  • Bug 848384 - Deprecate the SSL cipher policy code, as it’s no longer relevant. It is no longer necessary to call NSS_SetDomesticPolicy because all cipher suites are now allowed by default.

NSS 3.15.2 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.15.2 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.
