GLSA-200909-13 : irssi: Execution of arbitrary code

medium Nessus Plugin ID 40960

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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.
 Impact :

 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.
 Workaround :

 There is no known workaround at this time.

Solution

All irssi users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/irssi-0.8.13-r1'
