Description

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.
