WeeChat: Denial of Service

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-irc/weechat	< 0.2.6.1	>= 0.2.6.1	All supported architectures

Related bugreports: #262997

A processing error in WeeChat might lead to a Denial of Service.

2. Impact Information

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).

3. Resolution Information

There is no known workaround at this time.

All WeeChat users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/weechat-0.2.6.1"
