Apple Releases Security Update 2003-08-14 -- Apple has released Security Update 2003-08-14 for Mac OS X, a 1.1 MB download available via Software Update. The release corrects an off-by-one programming error in a FreeBSD networking function which could potentially be exploited to give a remote user root-level access to a Mac OS X system. The problem was originally found in the wu-ftpd FTP server, and impacts FreeBSD Unix and other FreeBSD-derived operating systems, including Solaris and some flavors of Linux. As of this writing, Apple has not provided any substantive information about the update; however, there are no known instances of this potential problem having been exploited under Mac OS X or any other operating system.

Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
