Package        : mc
Problem type   : local DoS
Debian-specific: no

Maurycy Prodeus found a problem in cons.saver, a screensaver for
the console that is included in the mc package. cons.saver does not
check if it is started with a valid stdout, which combined with a
bug in its check to see if its argument is a tty (it forgot to
close the file-descriptor after opening the supposed tty) causes it
to write a NUL character to the file given as its parameter.

This has been fixed in version 4.5.42-11.

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


Debian GNU/Linux 2.2 alias potato
