Severity:	high
Title:	Typespeed: Remote execution of arbitrary code
Date:	06/19/2006
Bugs:	#135071
ID:	200606-20

Synopsis

A buffer overflow in the network code of Typespeed can lead to the execution of arbitrary code.

Background

Typespeed is a game to test and practice 10-finger-typing. Network code allows two users to compete head-to-head.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
games-misc/typespeed	< 0.5.0	>= 0.5.0	All supported architectures

Description

Niko Tyni discovered a buffer overflow in the addnewword() function of Typespeed's network code.

Impact

By sending specially crafted network packets to a machine running Typespeed in multiplayer mode, a remote attacker can execute arbitrary code with the permissions of the user running the game.

Workaround

Do not run Typespeed in multiplayer mode. There is no known workaround at this time for multiplayer mode.

Resolution

All Typespeed users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=games-misc/typespeed-0.5.0"
