Along with OS X 10.9.2 (see “10.9.2 Fixes Critical SSL Security Bug, Adds FaceTime Audio,” 25 February 2014), Apple has released Security Update 2014-001 with security fixes for those still using OS X 10.8 Mountain Lion, 10.7 Lion, and 10.7 Lion Server. Alas, it seems that people running 10.6 Snow Leopard are now out in the cold, since this is the first security update to drop Snow Leopard-specific fixes. Security Update 2014-001 doesn’t need to address the recently discovered SSL/TLS security vulnerability (see “Apple Updates iOS and Apple TV to Fix Critical SSL Security Bug,” 24 February 2014) because it doesn’t affect versions of Mac OS X prior to 10.9. But the fixes it provides are still significant, addressing vulnerabilities in app sandboxing, font handling, image display, Nvidia drivers, Quick Look, QuickTime, and the system clock, along with the Apache Web server and PHP scripting language. (All updates are free. For 10.8 Mountain Lion, 115.8 MB; for 10.7 Lion, 123.4 MB; for 10.7 Lion Server, 173.6 MB.)
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.

Not being able to upgrade with the Security Upgrade concerns me, but I don't want an OS that overwhelms my CPU.
