"A bug exists in xinetd as shipped with Mandrake Linux 8.0 dealing with
TCP connections with the WAIT state that prevents linuxconf-web from
working properly. As well, xinetd contains a security flaw in which it
defaults to a umask of 0. This means that applications using the
xinetd umask that do not set permissions themselves (like SWAT, a web
configuration tool for Samba), will create world-writable files. This
update sets the default umask to 022.

Update :

This update forces the TMPDIR to /tmp instead of obtaining it from the
root user by default, which uses /root/tmp. As well, this version of
xinetd also fixed a possible buffer overflow in the logging code that
was reported by zen-parse on bugtraq, but was not mentioned in the
previous advisory."
