Although Oracle was planning to wait until April to update Java to address CVE-2013-1493, Java 7 Update 17 was released by Oracle today. Security Alert CVE-2013-1493 (http://www.oracle.com/technetwork/topics/security/alert-cve-2013-1493-1915081.html) addresses two vulnerabilities affecting Java running in web browsers (CVE-2013-1493 and CVE-2013-0809).
If Java is still installed on your computer, it is recommended that this update be applied as soon as possible due to the threat posed by a successful attack.
