TITLE:
Gentoo nethack / falconseye / slashem Privilege Escalation

SECUNIA ADVISORY ID:
SA19376

VERIFY ADVISORY:
http://secunia.com/advisories/19376/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Gentoo Linux 1.x
http://secunia.com/product/339/

DESCRIPTION:
Gentoo has reported some vulnerabilities in the nethack / falconseye
/ slashem packages, which can be exploited by malicious, local users
to gain escalated privileges.

The vulnerabilities are caused due to NetHack, Slash'EM, and Falcon's
Eye games being incompatible with the system used for managing games
on Gentoo Linux. This can be exploited by a user, who is a member of
the "games" group, to modify the state data, create and overwrite
files, and execute arbitrary code with the permissions of other
players.

The vulnerabilities have been reported in the following packages:
* games-roguelike/nethack version 3.4.3-r1 and prior.
* games-roguelike/falconseye version 1.9.4a and prior.
* games-roguelike/slashem version 0.0.760 and prior.

SOLUTION:
The vendor recommends uninstalling the packages until a patch is
available, and avoid the adding of untrusted users into the "games"
group.

PROVIDED AND/OR DISCOVERED BY:
Reported by vendor.
