Apple last week posted Security Update 2006-004, which patches a number of potential vulnerabilities. Some updated components include AFP (Apple Filing Protocol) Server, Bluetooth Setup Assistant, Bom (which handles archive files), fetchmail, and gunzip. A number of image-related problems have been addressed as well that could enable malformed images to crash the computer or execute code. Also, changes in LaunchServices, OpenSSH, telnet, and WebKit deal with connecting to malicious servers or Web pages. The update is available via Software Update, or as stand-alone downloads for Mac OS X 10.3.9 Client (29.5 MB), Mac OS X 10.3.9 Server (42.7 MB), Mac OS X 10.4.7 Client (Intel) (8.3 MB), and Mac OS X 10.4.7 Client (PPC) (5.4 MB).
