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 changes.

  • 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 (bmo#1334114)
  • Fixed a possible crash on some Windows systems (bmo#1323150)
  • Fixed a compatibility issue with TLS clients that do not provide a
    list of supported key exchange groups (bmo#1330612)
