http://secunia.com/advisories/27008/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
FSD 2.x

DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in FSD, which
potentially can be exploited by malicious people to compromise a
vulnerable system.

1) A boundary error exists within the "sysuser::exechelp()" function
in sysuser.cc. This can be exploited to cause a buffer overflow by
sending a specially crafted "help" command with an overly long
parameter to a vulnerable server.

2) A boundary error exists within the
"servinterface::sendmulticast()" function in servinterface.cc. This
can be exploited to cause a buffer overflow by sending various
specially crafted commands to a vulnerable server.

The vulnerabilities are reported in FSD 2.052 d9. Other versions may
also be affected.

SOLUTION:
Restrict use to trusted network environments.
