Oracle has provide his Java Critical Patch Update (CPU) for February 2013 how has been released on Friday, February 1.

On the 50 security vulnerabilities, fixed in this CPU, 49 of them may be remotely exploitable. The highest CVSS Base Score for vulnerabilities in this CPU is 10.0. 34 vulnerabilities have a CVSS base score upper or equal to 7.0.
It is actually not clear which of these vulnerability is exploited in the wild, but it could be related to CVE-2013-1489, an issue publicly reported and regarding Java SE7 security features introduced in Java SE7 Update 10.
As you may know Oracle is using CVSS 2.0 (Common Vulnerability Scoring System) in order to score the reported vulnerabilities. But as you also may know security researchers disagree with the usage of CVSS by Oracle. Oracle play with CVSS score by creating a “Partial+” impact rating how don’t exist in CVSS 2.0, and by interpreting the “Complete” rating in a different way than defined in CVSS 2.0.
