    Max Vozeler discoveredt hat the lockmail program from maildrop, a
    simple mail delivery agent with filtering abilities, does not drop
    group privileges before executing commands given on the commandline,
    allowing an attacker to execute arbitrary commands under with group
    mail privileges.
