Freeciv: User-assisted execution of arbitrary code

Background

Freeciv is an open-source empire building strategy game.

Description

The Lua component of Freeciv does not restrict which modules may be loaded by scenario scripts.

Impact

A remote attacker could entice a user to open a specially crafted scenario file, possibly resulting in execution of arbitrary code or reading of arbitrary files with the privileges of the process.

Workaround

There is no known workaround at this time.

Resolution

All Freeciv users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=games-strategy/freeciv-2.2.1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since July 26, 2010. It is likely that your system is already no longer affected by this issue.
