More information:

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.
