    Package        : exim4
    CVE ID         : CVE-2016-1531
    
    A local root privilege escalation vulnerability was found in Exim,
    Debian's default mail transfer agent, in configurations using the
    'perl_startup' option (Only Exim via exim4-daemon-heavy enables Perl
    support).
    
    To address the vulnerability, updated Exim versions clean the complete
    execution environment by default, affecting Exim and subprocesses such
    as transports calling other programs, and thus may break existing
    installations. New configuration options (keep_environment,
    add_environment) were introduced to adjust this behavior.
