Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE Id         : CAN-2003-0358

The falconseye package is vulnerable to a buffer overflow exploited
via a long '-s' command line option.  This vulnerability could be used
by an attacker to gain gid 'games' on a system where falconseye is
