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

Background
==========
Eggdrop is an IRC bot extensible with C or Tcl.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========
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
======
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
==========
There is no known workaround at this time.

Resolution

All Eggdrop users should upgrade to the latest version:

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