Package        : xinetd
Problem type   : change default umask
                 buffer overflow
Debian-specific: no

zen-parse reported on bugtraq that there is a possible buffer overflow
in the logging code from xinetd. This could be triggered by using a
fake identd that returns special replies when xinetd does an ident
request.

Another problem is that xinetd sets it umask to 0. As a result any
programs that xinetd start that are not careful with file permissions
will create world-writable files.

Both problems have been fixed in version 2.1.8.8.p3-1.1 .

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
