"About Java for Mac OS X 10.6 Update 13
Java for Mac OS X 10.6 Update 13 delivers improved security, reliability, and compatibility by updating Java SE 6 to 1.6.0_41.

Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.

Please quit any web browsers and Java applications before installing this update.

As with the previous updates IIRC, today's updates from Apple also check for existing Malware and will remove it if found.

I don't use Java but you can check Apple's OS X Forums for feedback from those that do.
(On a related note, reportedly some Macs were compromised due to Java plugin vulnerabilities. BTW: Google safe browsing check (2-19-2013) reported a couple pages (out of 21000+ tested) at Apple.com as suspicious. ("2 page(s) resulted in malicious software being downloaded and installed without user consent.... Malicious software includes 3 virus, 1 trojan(s)"). I wish they included specific pages in their reports. Saw another report on Jan 15, 2013 and IIRC a couple times last year. Some other popular sites have far worse/more frequent cases however.)
  

"About Java for OS X 2013-001
Java for OS X 2013-001 delivers improved security, reliability, and compatibility by updating Java SE 6 to 1.6.0_41.

On systems that have not already installed Java for OS X 2012-006, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled "Missing plug-in" to download the latest version of the Java applet plug-in from Oracle.

Please quit any web browsers and Java applications before installing this update.

SHA1=145d74354241cf2f567d2768bbd0a7185e7d308a

System Requirements:
OS X SnowLeopard v10.6 or later (incorrect)
OS X Lion v10.7 or later
OS X Mountain Lion v10.8 or later"

Download page also lists OS X 10.6, but I think that's a typo as the "About" doc says "OS X 10.7 and later". (Separate Java for OS X 10.6 update 13 (above) covers 10.6.x and this update is for OS X Lion/Mountain Lion. I'm on a 10.5.8 machine currently and can't check that but it was later confirmed by BDA.) [A few days later they corrected a misspelling of Mountain on the D/L page but OS X 10.6 or later remains.]
