 Hичего особенного, вот выдержка из дебиановского сообщения, другие
 примерно это же писали, но debian подробнее.

 Package        : exim
 Vulnerability  : Uncontrolled program execution
 Problem-Type   : remote vulnerability
 Debian-specific: no
 
 Patrice Fournier discovered a bug in all versions of Exim older than
 Exim 3.34 and Exim 3.952.
 
 The Exim maintainer, Philip Hazel, writes about this issue: "The
 problem exists only in the case of a run time configuration which
 directs or routes an address to a pipe transport without checking the
 local part of the address in any way.  This does not apply, for
 example, to pipes run from alias or forward files, because the local
 part is checked to ensure that it is the name of an alias or of a
 local user.  The bug's effect is that, instead of obeying the correct
 pipe command, a broken Exim runs the command encoded in the local part
 of the address."
 
 This problem has been fixed in Exim version 3.12-10.2 for the stable
 distribution Debian GNU/Linux 2.2 and 3.33-1.1 for the testing and
 unstable distribution.  We recommend that you upgrade your exim
 package.
