The remote Scientific Linux host is missing one or more security
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
