(Debian Issues Fix) xtokkaetama Buffer Overflows Let Local Users Gain 'Games' Group Privileges
SecurityTracker Alert ID:  1007352
SecurityTracker URL:  http://securitytracker.com/id/1007352
CVE Reference:   CVE-2003-0611   (Links to External Site)
Date:  Jul 31 2003
Impact:   Execution of arbitrary code via local system, User access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.0b
Description:   A buffer overflow vulnerability was reported in the xtokkaetama puzzle game. A local user can gain elevated group privileges.

A local user can reportedly supply a specially crafted '-display' command line option or set a specially crafted XTOKKAETAMADIR environment variable to trigger either of two buffer overflows and execute arbitrary code. The code will run with set group id (setgid) 'games' group privileges.

Debian credited Steve Kemp with reporting the flaw.

Impact:   A local user can execute arbitrary code with 'games' group privileges.
Solution:   Debian has released a fix for the current stable distribution (woody) in version 1.0b-6woody1 and for the unstable distribution (sid) in version 1.0b-8.
