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 installed. Note that falconseye does not contain the file permission error CVE-2003-0359 which affected some other nethack packages. For the stable distribution (woody) this problem has been fixed in version 1.9.3-7woody3. For the unstable distribution (sid) this problem has been fixed in version 1.9.3-9. We recommend that you update your falconseye package.
