Ubuntu 8.04 LTS / 9.04 / 9.10 / 10.04 LTS / 10.10 : nss vulnerabilities (USN-1007-1)

Ubuntu Security Notice (C) 2010-2014 Canonical, Inc. / NASL script (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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 :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
