The remote host is missing updates announced in advisory GLSA 200407-07.

All users should upgrade to the latest available version of Shorewall, as follows: # emerge sync # emerge -pv '>=net-firewall/shorewall-1.4.10f' # emerge '>=net-firewall/shorewall-1.4.10f' http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200407-07 http://bugs.gentoo.org/show_bug.cgi?id=55675 http://lists.shorewall.net/pipermail/shorewall-announce/2004-June/000385.html

Shorewall contains a bug in the code handling the creation of temporary files and directories. This can allow a non-root user to overwrite arbitrary system files.
