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.
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
backported support for the new RFC5746 renegotiation extension and
will use it when both the client and the server support it.
ATTENTION: After applying this update, a patched server will allow
both patched and unpatched clients to connect, but unpatched clients
will not be able to renegotiate. For more information, please refer to
Update the affected packages.
