nss - security update

In nss, a set of libraries designed to support cross-platform
development of security-enabled client and server applications, Tyson
Smith and Jesse Schwartzentruber discovered a use-after-free
vulnerability that allows remote attackers to execute arbitrary code by
triggering the improper removal of an NSSCertificate structure from a
trust domain.

For the stable distribution (wheezy), this problem has been fixed in
version 2:3.14.5-1+deb7u3.

For the upcoming stable distribution (jessie), this problem has been
fixed in version 2:3.16.3-1.

For the unstable distribution (sid), this problem has been fixed in
