The discovery of in-the-wild attacks exploiting a vulnerability in Oracle's Java 7 caused a flap this week.
The next Java update was scheduled for October 16, but overnight Oracle released Java 7 Update 7 to fix the vulnerability, which has been used to deliver Windows malware.
Update 7 also includes fixes for two other vulnerabilities affecting Java running in desktop web browsers.
Java 7 Update 7 and Java 6 Update 35 can be downloaded here, though Windows users may prefer to take advantage of the automatic update feature.
Mac users can download Java 7 Update 7 via the above link, but those still on Java 6 will have to wait until Apple releases the update.
