The remote Red Hat host is missing one or more security updates.
Updated postfix packages that include a security fix and two other bug
fixes are now available for Red Hat Enterprise Linux 4.
This update has been rated as having low security impact by the Red
Hat Security Response Team
Postfix is a Mail Transport Agent (MTA), supporting LDAP, SMTP AUTH
(SASL), and TLS.
A flaw was found in the ipv6 patch used with Postfix. When the file
/proc/net/if_inet6 is not available and permit_mx_backup is enabled in
smtpd_recipient_restrictions, this flaw could allow remote attackers
to bypass e-mail restrictions and perform mail relaying by sending
mail to an IPv6 hostname. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2005-0337 to this
These updated packages also fix the following problems :
- wrong permissions on doc directory - segfault when
gethostbyname or gethostbyaddr fails
All users of postfix should upgrade to these updated packages, which
contain patches which resolve these issues.
