Mac OS X 10.5.1 Update
Following a slew of updates yesterday, Apple today released the Mac OS X 10.5.1 Update for its recently released Leopard operating system. The update brings more than a dozen fixes for AirPort, Back to My Mac, Disk Utilities, iCal, Mail, Networking, Printing, Security/Firewall, System and Finder, and Time Machine. The update is available via the Web (110MB) and the Software Update (40MB). In addition to the bug fixes, Apple also said that the update fixes three security flaws in the firewall.
In addition to the bug fixes, Apple also said that the update fixes three security flaws in the firewall. Apple noted that the "Block all incoming connections" setting for the firewall is misleading and changed it to "Allow Essential Connections," as it allows any process running as user "root" (UID 0) to receive incoming connections, and also allows mDNSResponder to receive connections. Apple said the update limits the processes permitted to receive incoming connections under this setting to a small fixed set of system services: configd (for DHCP and other network configuration protocols), mDNSResponder (for Bonjour), and racoon (for IPSec). Improves the reliability of Back to My Mac-enabled Macs appearing in the Finder's Shared Sidebar.
Apple also notes that the updates fixes an issue in the new operating system where processes running as user "root" (UID 0) cannot be blocked when the firewall is set to "Set access for specific services and applications". It corrects the issue so that any executable so marked is blocked. This issue does not affect systems prior to Mac OS X v10.5.
Finally, the update also fixes an issue where changes to Application Firewall settings do not affect processes started by launchd until they are restarted, making so that changes take effect immediately.
Apple also said that update now allows password-protected accounts on AirPort Disks to show up on in the Finder's Shared Sidebar and resolves an issue with saved passwords for wireless networks. Other fixes include
