Test ID:	1.3.6.1.4.1.25623.1.0.68488
Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-1007-1 (nss)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to nss announced via advisory USN-1007-1. Details follow: Richard Moore discovered that NSS would sometimes incorrectly match an SSL certificate which had a Common Name that used a wildcard followed by a partial IP address. While it is very unlikely that a Certificate Authority would issue such a certificate, if an attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2010-3170) Nelson Bolyard discovered a weakness in the Diffie-Hellman Ephemeral mode (DHE) key exchange implementation which allowed servers to use a too small key length. (CVE-2010-3173) Solution: The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: libnss3-1d 3.12.8-0ubuntu0.8.04.1 Ubuntu 9.04: libnss3-1d 3.12.8-0ubuntu0.9.04.1 Ubuntu 9.10: libnss3-1d 3.12.8-0ubuntu0.9.10.1 Ubuntu 10.04 LTS: libnss3-1d 3.12.8-0ubuntu0.10.04.1 Ubuntu 10.10: libnss3-1d 3.12.8-0ubuntu0.10.10.1 After a standard system update you need to restart any applications that use NSS, such as Firefox, Thunderbird or Evolution, to make all the necessary changes. This update also includes updated NSPR packages to work with the new NSS. http://www.securityspace.com/smysecure/catid.html?in=USN-1007-1 Risk factor : High CVSS Score: 7.5
