Like all software in life, there are times when a security flaw is identified and a fix (patch) is published.
Debian Linux uses a convenient method to keep up with security.
Make sure the file /etc/apt/sources.list contains a line like this:
deb http://security.debian.org/ etch/updates
main contrib non-free
Periodically do this:
aptitude update
aptitude upgrade
