Debian Security Advisory DSA 097-1                     security@debian.org

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.
