Wee Enhanced Environment for Chat (WeeChat) is a light and extensible console IRC client.
Sebastien Helleu reported an array out-of-bounds error in the colored message handling.
A remote attacker could send a specially crafted PRIVMSG command, possibly leading to a Denial of Service (application crash).
There is no known workaround at this time.
All WeeChat users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/weechat-0.2.6.1"
