Bug#606612: exim4: Exploitable memory corruption vulnerability

[Dominic Hargreaves]

Package: exim4
Version: 4.69-9
Severity: critical
Tags: security
Justification: root security hole

There is a discussion on exim-dev[0] relating to an incident of root-level
compromise owing to a couple of bugs. The first (the remote attack)
appears[1] to be related to a bug already fixed in mainline[2].

I hadn't seen any response from any Debian people on this (publically
at least) so I thought it would be worth filing this bug, to make
sure the right people are aware of the issue.

Cheers,
Dominic.
