Red Hat Security Errata

The tog-pegasus package is not installed by default on Red Hat Enterprise Linux.
tog-pegasus supplied by Red Hat binds only to one port (as plain http is
disabled), port 5989. The default firewall installed by Red Hat Enterprise
Linux will block remote access to this port. In normal use it's unlikely you'd
want to have this port accessible outside of an intranet anyway, and it's likely
to be blocked by enterprise border firewalls.
However if tog-pegasus has been installed and unblocked through the fireware,
the Red Hat Security Response Team believes that it would still be hard to
remotely exploit this issue to execute arbitrary code due to the default SELinux
targeted policy on Enterprise Linux 4 and 5, and the SELinux memory protections
enabled by default on Enterprise Linux 5.
