Description

modules/m_capab.c in (1) ircd-ratbox before 3.0.8 and (2) Charybdis before 3.4.2 does not properly support capability negotiation during server handshakes, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a malformed request.

Solution(s)

  • gentoo-linux-upgrade-net-irc-charybdis
  • gentoo-linux-upgrade-net-irc-shadowircd
