Vulnerability Assessment Details

[GLSA-200603-26] bsd-games: Local privilege escalation in tetris-bsd

Vulnerability Assessment Summary
bsd-games: Local privilege escalation in tetris-bsd

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-26
(bsd-games: Local privilege escalation in tetris-bsd)


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 rights of other players.

Workaround

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


Solution:
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"


Network Security Threat Level: Medium
