tag_insight = "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.
  
  Red Hat would like to thank the CERT/CC for reporting this issue. Upstream
  acknowledges Thomas Jarosch of Intra2net AG as the original reporter.
  
  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 automatically.";
