Summary

The remote host is missing an update for the 'sa-exim' package(s) announced via the DSA-2062-1 advisory.

Insight

Insight

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.
