Gentoo Linux Security Advisory

Title: Scorched 3D server chat box format string vulnerability (GLSA 200404-12)
Severity: high
Exploitable: remote
Date: April 09, 2004
Bug(s): #39302
ID: 200404-12

Synopsis


Scorched 3D is vulnerable to a format string attack in the chat box that
leads to Denial of Service on the game server and possibly allows execution
of arbitrary code.


Background


Scorched 3D is a game based loosely on the classic DOS game "Scorched
Earth". Scorched 3D adds amongst other new features a 3D island
environment and LAN and internet play. Scorched 3D is totally free and is
available for multiple operating systems.


Affected Packages

Package: games-strategy/scorched3d
Vulnerable: < 37
Unaffected: >= 37
Architectures: All supported architectures


Description


Scorched 3D (build 36.2 and before) does not properly check the text
entered in the Chat box (T key). Using format string characters, you can
generate a heap overflow. This and several other unchecked buffers have
been corrected in the build 37 release.


Impact


This vulnerability can be easily exploited to remotely crash the Scorched
3D server, disconnecting all clients. It could also theorically be used to
execute arbitrary code on the server with the rights of the user running
the server.


Workaround


A workaround is not currently known for this issue. All users are advised
to upgrade to the latest version of the affected package.


Resolution


Scorched 3D users should upgrade to version 37 or later:
