<p>
|
|
Nemo discovered an off-by-one error leading to a heap overflow in
|
|
irssi's event_wallops() parsing function.

<impact type="high">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All irssi users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-irc/irssi-0.8.13-r1"</code>
