|
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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not add untrusted users to the "games" group.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All bsd-games users are advised to update to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=games-misc/bsd-games-2.17-r1"</code>
|
|
</resolution>
