Typespeed is a game to test and practice 10-finger-typing. Network code allows two users to compete head-to-head.
Niko Tyni discovered a buffer overflow in the addnewword() function of Typespeed's network code.
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.
Do not run Typespeed in multiplayer mode. There is no known workaround at this time for multiplayer mode.
All Typespeed users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=games-misc/typespeed-0.5.0"
