Severity: Normal Title: bsd-games: Local privilege escalation in tetris-bsd Date: March 29, 2006 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 games-misc/bsd-games < 2.17-r1 >= 2.17-r1
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=games-misc/bsd-games-2.17-r1"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200603-26.xml
Concerns? =========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
