"Updated spamassassin packages that fix a security issue are now
available for Red Hat Enterprise Linux 4 and 5.

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.

Martin Krafft discovered a symlink issue in SpamAssassin that affects
certain non-default configurations. A local user could use this flaw
to create or overwrite files writable by the spamd process
(CVE-2007-2873).

Users of SpamAssassin should upgrade to these updated packages which
contain a backported patch to correct this issue.

Note: This issue did not affect the version of SpamAssassin shipped
with Red Hat Enterprise Linux 3."
