Available now via Apple's Software Update
Apple has made available its Security Update 2007-009 which can be downloaded and installed via Apple's Software Update, or from Apple Downloads.
The updates, available for Mac OS X v10.4.11 and Mac OS X v10.5.1, correct flaws that Apple say could lead to "unexpected application termination or arbitrary code execution."
Contained within the update are fixes for Address Book, CFNetwork, ColorSync, Core Foundation, CUPS, Desktop Services, Flash Player Plug-in, GNU Tar, iChat, IO Storage Family, Launch Services, Mail, perl, python, Quick Look, ruby, Safari, Safari RSS, Samba, Shockwave Plug-in, SMB, Software Update, Spin Tracer, Spotlight, tcpdump and XQuery.
Phew, that's a whole lot of fixes right there. Thorough details on each of the problems can be found in Apple's documentation.
The Apple security updates come hot on the heels of Microsoft's security updates last week as both companies end the year by making security an on-going focus.
