Ubuntu 5.10 / 6.06 LTS / 6.10 : fetchmail vulnerability (USN-405-1)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that fetchmail did not correctly require TLS
negotiation in certain situations. This would result in a user's
unencrypted password being sent across the network.

If fetchmail has been configured to use the 'sslproto tls1',
'sslcertck', or 'sslfingerprint' options with a server that does not
correctly support TLS negotiation, this update may cause fetchmail to
(correctly) abort authentication.

Solution :

Update the affected fetchmail, fetchmail-ssl and / or fetchmailconf
packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:C/I:N/A:N)
