RHEL 4 : postfix (RHSA-2005:152)

critical Nessus Plugin ID 17339

Synopsis

The remote Red Hat host is missing a security update for postfix.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2005:152 advisory.

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 CAN-2005-0337 to this issue.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL postfix package based on the guidance in RHSA-2005:152.
