Exim is a message transfer agent (MTA) designed to be a a highly configurable, drop-in replacement for sendmail.
It was discovered that Exim incorrectly handled certain string operations.
A remote attacker, able to connect to a vulnerable Exim instance, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All Exim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/exim-4.92.3"
