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

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

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)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
