Gentoo Linux Security Advisory

Title: bsd-games: Local privilege escalation in tetris-bsd (GLSA 200603-26)
Severity: normal
Exploitable: local
Date: March 29, 2006
Updated: May 22, 2006
Bug(s): #122399
ID: 200603-26

Synopsis

tetris-bsd is prone to local privilege escalation vulnerabilities.

Background

bsd-games is a collection of NetBSD games ported to Linux.

Affected Packages

Package: games-misc/bsd-games
Vulnerable: < 2.17-r1
Unaffected: >= 2.17-r1
Architectures: All supported architectures


Description

Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that the checkscores() function in scores.c reads in the data from the /var/games/tetris-bsd.scores file without validation, rendering it vulnerable to buffer overflows and incompatible with the system used for managing games on Gentoo Linux. As a result, it cannot be played securely on systems with multiple users. Please note that this is probably a Gentoo-specific issue.

Impact

A local user who is a member of group "games" may be able to modify the tetris-bsd.scores file to trigger the execution of arbitrary code with the privileges of other players.

Workaround

Do not add untrusted users to the "games" group.

Resolution

All bsd-games users are advised to update to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=games-misc/bsd-games-2.17-r1"
