 Oracle release a security bulletin yesterday relating to the binary floating point issue when converting 2.2250738585072012e-308" to a binary floating-point number.  (http://www.oracle.com/technetwork/topics/security/alert-cve-2010-4476-305811.html)

The problem affects both JRE and JDK 6 update 23 and earlier. 4.0 Update 27 and earlier, as well as,  yes people still use it, SDK & JRE 1.4.2_29.

Applications utilising these versions will be vulnerable to denial of service attacks.  Servlet managers such as tomcat and others are likely affected as these often run older versions of java.  

No patch available just yet.

The Oracle security bulletin references a patch - http://www.oracle.com/technetwork/java/javase/downloads/index.html#fpupdater . It's not an updated version, just a tool that patches all the various affected versions. See the Readme (http://www.oracle.com/technetwork/java/javase/fpupdater-tool-readme-305936.html) for tons of details.
