Submission + - Mac OS X Leopard's firewall wide open! (

rpp3po writes: German tech magazine Heise analyzed Leopard's new firewall and made some shocking discoveries. Even when you set it to "block all incoming connections" at least 4 ports are left wide open (ntpd, netbios, mdns). Additionally "Apple uses ntpd 4.2.2, the current version is 4.2.4. It is not clear whether any of the bug fixes are relevant in this scenario and if Apple back-ported fixes from more recent versions."
