CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
Liero Xtreme 0.x
http://secunia.com/product/8585/

DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in Liero Xtreme,
which can be exploited by malicious people to cause a DoS (Denial of
Service) and potentially compromise a user's system.

1) An error within the handling of the "connect" command can be
exploited to crash the server or to cause it to stop responding via
an overly long string passed to the command.

2) A format string error in the client can potentially be exploited
to execute arbitrary code via a specially-crafted nickname or
mapname. This can e.g. be exploited by hosting a malicious dedicated
server with a specially-crafted server name.

The vulnerabilities have been reported in version 0.62b and prior.

SOLUTION:
Host network games only within trusted networks and do not connect to
non-trusted game servers.
