OPERATING SYSTEM:

DESCRIPTION:
Some weaknesses and a security issue have been reported in Apple Mac
OS X, which can lead to exposure of certain services.

1) The Application Firewall allows any process running as user "root"
(UID 0) to receive incoming connections even though the option "Block
all incoming connections" is set.

NOTE: The update changes the name of the option and updates the
documentation.

2) The Application Firewall allows any process running as user "root"
(UID 0) to receive incoming connections even though the executable has
been added to the list of blocked applications via the "Set access for
specific services and applications" option.

3) Changes to Application Firewall settings do not affect processes
started by launchd until they are restarted. This may lead to
exposure of certain services.
