Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
USN-927-1 fixed vulnerabilities in NSS. Due to upstream changes in NSS
3.12.6, Thunderbird would be unable to initialize the security
component and connect with SSL/TLS if the old libnss3-0d transition
package was installed. This update fixes the problem.
We apologize for the inconvenience.
Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3
protocols. If an attacker could perform a man in the middle attack at
the start of a TLS connection, the attacker could inject arbitrary
content at the beginning of the user's session. This update adds
support for the new new renegotiation extension and will use it when
the server supports it.
Update the affected packages.
