Package        : exim
Problem type   : remote printf format attack
Debian-specific: no

Megyer Laszlo found a printf format bug in the exim mail transfer
agent. The code that checks the header syntax of an email logs
an error without protecting itself against printf format attacks.

This problem has been fixed in version 3.12-10.1. Since that code is
not turned on by default a standard installation is not vulnerable,
but we still recommend to upgrade your exim package.

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


Debian GNU/Linux 2.2 alias potato
---------------------------------

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
