Scientific Linux Security Update : postfix on SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

It was discovered that Postfix did not flush the received SMTP
commands buffer after switching to TLS encryption for an SMTP session.
A man-in-the-middle attacker could use this flaw to inject SMTP
commands into a victim's session during the plain text phase. This
would lead to those commands being processed by Postfix after TLS
encryption is enabled, possibly allowing the attacker to steal the
victim's mail or authentication credentials. (CVE-2011-0411)

After installing this update, the postfix service will be restarted
automatically.
