RHEL 4 : spamassassin (RHSA-2006:0543)

This script is Copyright (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated spamassassin packages that fix an arbitrary code execution
flaw are now available.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

SpamAssassin provides a way to reduce unsolicited commercial email
(SPAM) from incoming email.

A flaw was found with the way the Spamassassin spamd daemon processes
the virtual pop username passed to it. If a site is running spamd with
both the --vpopmail and --paranoid flags, it is possible for a remote
user with the ability to connect to the spamd daemon to execute
arbitrary commands as the user running the spamd daemon.

Note: None of the IMAP or POP servers shipped with Red Hat Enterprise
Linux 4 support vpopmail delivery. Running spamd with the --vpopmail
and --paranoid flags is uncommon and not the default startup option as
shipped with Red Hat Enterprise Linux 4.

Spamassassin, as shipped in Red Hat Enterprise Linux 4, performs RBL
lookups against visi.com to help determine if an email is spam.
However, this DNS RBL has recently disappeared, resulting in mail
filtering delays and timeouts.

Users of SpamAssassin should upgrade to these updated packages
containing version 3.0.6 and backported patches, which are not
vulnerable to these issues.
