Debian DSA-2994-1 Moderate: NSS Certificate Issues and Fixes

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.

Furth...
