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.");
