Details:
A vulnerability was discovered in the "sort" expansion operator:
The elements of the list were expanded, giving a possible attack
if the list included data supplied by an attacker.
If the effective configuration file for exim does not use sort
then the system is trivially declarable as not being vulnerable.
Use this command to check: "exim -bP config | grep sort".
