<p>Exim is a message transfer agent (MTA) designed to be a a highly
configurable, drop-in replacement for sendmail.
<p>Vulnerabilities have been discovered in Exim’s implementation of
set-uid root and when using ‘perl_startup’. These vulnerabilities
require a user account on the Exim server and a configuration that does
lookups against files to which the user has edit access.
<impact type="normal">
<p>A local attacker could possibly execute arbitrary code with the
privileges of the process, or escalate privileges.
<p>There is no known workaround at this time.</p>
<p>All Exim users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=mail-mta/exim-4.87"
