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

high Nessus Plugin ID 27993

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.
