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	Architecture(s)

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.
