Description

Multiple Unix flavors that install the 'empire' game contain a flaw that may allow a local user to gain privileges. The issue is due to the program not dropping SGID privileges when invoking commands. This can be used to execute a sub-process with the same privileges as the game, allowing any command to be run with the same group ID.

Classification

Location: Local Access Required
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public

Solution

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: remove the SUID bit from the program.
