Just noticed the jumping software update icon in the dock of my server which I regularly check using Chicken of the VNC. It looks from the knowledge base article that this is mostly an update to prevent security breaches with malicious code using buffer overflow problems. The items that where updated included: AppKit, Bom, CFNetwork, ClamAV, CoreFoundation, CoreGraphics, libcurl, Finder, FTP-Server, KeyChain, ImageIO, LaunchServices, QuickDraw, Ruby and Safari.

I’ve updated the Mac mini server and there were no noticeable issues after installing the update.
