Title:	CentOS Update for postfix CESA-2011:0843 centos4 i386
Summary:	The remote host is missing an update for the 'postfix'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'postfix' package(s) announced via the referenced advisory. Vulnerability 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. Affected Software/OS: postfix on CentOS 4 Solution: Please install the updated packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
