    It was found that sa-exim, the SpamAssassin filter for Exim, allows
    attackers to execute arbitrary code if users are allowed to run custom
    rules. A similar issue was fixed in spamassassin, CVE-2018-11805, which
    caused a functional regression in sa-exim. This update restores the
    compatibility between spamassassin and sa-exim. The security
    implications of sa-exim's greylisting function are also documented in
    /usr/share/doc/sa-exim/README.greylisting.gz.
    
    For Debian 8 "Jessie", this problem has been fixed in version
    4.2.1-14+deb8u1.
    
    We recommend that you upgrade your sa-exim packages.
