The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200909-13
(irssi: Execution of arbitrary code)
Nemo discovered an off-by-one error leading to a heap overflow in
irssi's event_wallops() parsing function.
A remote attacker might entice a user to connect to a malicious IRC
server, use a man-in-the-middle attack to redirect a user to such a
server or use ircop rights to send a specially crafted WALLOPS message,
which might result in the execution of arbitrary code with the
privileges of the user running irssi.
There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-irc/irssi-0.8.13-r1'
