Synopsis

Multiple vulnerabilities have been found in the network components of UFO2000 that could result in the remote execution of arbitrary code.

2. Impact Information

Background

UFO2000 is a multi-player, turn-based tactical simulation.

Description

Five vulnerabilities were found: a buffer overflow in recv_add_unit(); a problem with improperly trusting user-supplied string information in decode_stringmap(); several issues with array manipulation via various commands during play; an SQL injection in server_protocol.cpp; and finally, a second buffer overflow in recv_map_data().

Impact

An attacker could send crafted network traffic as part of a multi-player game that could result in remote code execution on the remote opponent or the server. A remote attacker could also run arbitrary SQL queries against the server account database, and perform a Denial of Service on a remote opponent by causing the game to crash.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

UFO2000 currently depends on the dumb-0.9.2 library, which has been removed from portage due to security problems (GLSA 200608-14) . Because of this, UFO2000 has been masked, and we recommend unmerging the package until the next beta release can remove the dependency on dumb.

Code Listing 3.1: Resolution

# emerge --ask --verbose --unmerge ufo2000
