Apple’s sticking with the new security update naming convention. Security Update 2005-002 is primarily a Java fix.
According to Apple:
Security Update 2005-002
Available for: Java 1.4.2
Impact: Updates Java to address an issue where an untrusted applet could gain elevated privileges and potentially execute arbitrary code.
But what does that mean Professor? One of the rules of untrusted Java applets was that they had no access to the hosting computer’s filesystem. This prevents things like collecting your personal information and sending it to their servers (and then to spammers). It also prevents modifications to your data and prevents things from being written out, like say the Opener malware. Not good.
Anyway, run software update so you too can feel warm and fuzzy inside.
