GLSA 200603-10: Cube: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	high
Title:	Cube: Multiple vulnerabilities
Date:	03/13/2006
Bugs:	#125289
ID:	200603-10

Synopsis

Cube is vulnerable to a buffer overflow, invalid memory access and remote client crashes, possibly leading to a Denial of Service or remote code execution.

Background

Cube is an open source first person shooter game engine supporting multiplayer via LAN or internet.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
games-fps/cube	<= 20050829		All supported architectures

Description

Luigi Auriemma reported that Cube is vulnerable to a buffer overflow in the sgetstr() function (CVE-2006-1100) and that the sgetstr() and getint() functions fail to verify the length of the supplied argument, possibly leading to the access of invalid memory regions (CVE-2006-1101). Furthermore, he discovered that a client crashes when asked to load specially crafted mapnames (CVE-2006-1102).

Impact

A remote attacker could exploit the buffer overflow to execute arbitrary code with the rights of the user running cube. An attacker could also exploit the other vulnerabilities to crash a Cube client or server, resulting in a Denial of Service.

Workaround

Play solo games or restrict your multiplayer games to trusted parties.

Resolution

Upstream stated that there will be no fixed version of Cube, thus the Gentoo Security Team decided to hardmask Cube for security reasons. All Cube users are encouraged to uninstall Cube:

    # emerge --ask --unmerge games-fps/cube
