high Nessus Plugin ID 76950
New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the nss packages.

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