Title:RedHat Security Advisory RHSA-2011:0843
The remote host is missing updates announced in
advisory RHSA-2011:0843.

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.

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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
