Scientific Linux Security Update : postfix on SL4.x, SL5.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

Description :

Postfix is a Mail Transport Agent (MTA), supporting LDAP, SMTP AUTH
(SASL), and TLS.

A heap-based buffer over-read flaw was found in the way Postfix
performed SASL handlers management for SMTP sessions, when Cyrus SASL
authentication was enabled. A remote attacker could use this flaw to
cause the Postfix smtpd server to crash via a specially crafted SASL
authentication request. The smtpd process was automatically restarted
by the postfix master process after the time configured with
service_throttle_time elapsed. (CVE-2011-1720)

Note: Cyrus SASL authentication for Postfix is not enabled by default.

Users of Postfix are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue. After
installing this update, the postfix service will be restarted
