    The bug's effect is that, instead of obeying the correctpipe command, a broken Exim runs the command encoded in the local partof the address.

    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
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
