nss - security update

Several vulnerabilities have been discovered in nss, the Mozilla Network
Security Service library:

• CVE-2013-1741
  Runaway memset in certificate parsing on 64-bit computers leading to
  a crash by attempting to write 4Gb of nulls.
• CVE-2013-5606
  Certificate validation with the verifylog mode did not return
  validation errors, but instead expected applications to determine
  the status by looking at the log.
• CVE-2014-1491
  Ticket handling protection mechanisms bypass due to the lack of
  restriction of public values in Diffie-Hellman key exchanges.
• CVE-2014-1492
  Incorrect IDNA domain name matching for wildcard certificates could
  allow specially-crafted invalid certificates to be considered as
  valid.

For the stable distribution (wheezy), these problems have been fixed in
version 2:3.14.5-1+deb7u1.

For the testing distribution (jessie), and the unstable distribution (sid),
these problems have been fixed in version 2:3.16-1.

We recommend that you upgrade your nss packages.
