A remote stack-based buffer overflow has been discovered in Eggdrop.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------
  1  net-irc/eggdrop      < 1.6.18-r2                     >=3D 1.6.18-r2

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Bow Sineath discovered a boundary error in the file
mod/server.mod/servrmsg.c when processing overly long private messages
sent by an IRC server.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could entice an Eggdrop user to connect the bot to a
malicious server, possibly resulting in the execution of arbitrary code
on the host running Eggdrop.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Eggdrop users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dnet-irc/eggdrop-1.6.18-r2"
