Apple almost made it through the month of July without an operating system security update which would have been a first for the year. But OS X Security Update 2007-007 was released on the last day of the month.
Thirteen components are updated. Click the thumbnail to see the component list or visit the Apple Support Page for the complete details. Of special note is the Samba vulnerability that Apple has finally patched. Samba is an open source windows file sharing application that is bundled with OS X. A critical vulnerability was found in late may and almost immediately patched by the Samba team. Apple has released several security updates since then but none have included the Samba patch, until now. Samba is off by default but is enabled when turning on Windows sharing in System Preference -> Sharing.
The update is for both Intel and PPC based Macs running OS X 10.3.9 or OS X 10.4.10 including the standard OS and the Server OS. It’s available through Apple’s built-in software update service or as a standalone download. A computer restart is needed after applying the patch.
Apple also released Airport Extreme Update 2007-004. Details are lacking and Apple’s only comment is:
This update is recommended for all Intel-based MacBook, MacBook Pro, and Mac mini computers and improves the reliability of AirPort connections.
