mozilla-nss was updated to NSS 3.28.3

- This is a patch release to fix binary compatibility
issues. NSS version 3.28, 3.28.1 and 3.28.2 contained
changes that were in violation with the NSS
compatibility promise. ECParams, which is part of the
public API of the freebl/softokn parts of NSS, had been
changed to include an additional attribute. That size
increase caused crashes or malfunctioning with
applications that use that data structure directly, or
indirectly through ECPublicKey, ECPrivateKey,
NSSLOWKEYPublicKey, NSSLOWKEYPrivateKey, or potentially
other data structures that reference ECParams. The
change has been reverted to the original state in bug
bmo#1334108. SECKEYECPublicKey had been extended with a
new attribute, named 'encoding'. If an application
passed type SECKEYECPublicKey to NSS (as part of
SECKEYPublicKey), the NSS library read the uninitialized
attribute. With this NSS release
SECKEYECPublicKey.encoding is deprecated. NSS no longer
reads the attribute, and will always set it to
ECPoint_Undefined. See bug bmo#1340103.

- requires NSPR >= 4.13.1

- update to NSS 3.28.2 This is a stability and
compatibility release. Below is a summary of the

- Fixed a NSS 3.28 regression in the signature scheme
flexibility that causes connectivity issues between iOS
8 clients and NSS servers with ECDSA certificates

- Fixed a possible crash on some Windows systems

- Fixed a compatibility issue with TLS clients that do not
provide a list of supported key exchange groups
