Synopsis: Moderate: postfix security update
Issue Date: 2011-05-31
CVE Numbers: CVE-2011-1720
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 automatically.
