RHEL 3 / 4 / 5 : postfix (RHSA-2008:0839)

medium Nessus Plugin ID 33893

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated postfix packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate 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 way Postfix dereferences symbolic links. If a local user has write access to a mail spool directory with no root mailbox, it may be possible for them to append arbitrary data to files that root has write permission to. (CVE-2008-2936)

Red Hat would like to thank Sebastian Krahmer for responsibly disclosing this issue.

All users of postfix should upgrade to these updated packages, which contain a backported patch that resolves this issue.

Solution

Update the affected postfix and / or postfix-pflogsumm packages.
