Partial Security Bypass Vulnerability in Java
No patch available. Oracle has deemed this vulnerability to be "allowed behavior".
Java SE 7 Update 17 and prior
Java SE does not include proper security checks within a family of MethodHandle resolving methods. This can be abused by attackers, in combination with another partial security bypass, to create a full sandbox bypass, which could be used to allow attackers to run arbitrary remote code within the context of the current user.
Oracle has stated that this issue is "allowed behavior", despite the notion that it can be used against end-users.
No. Requires a secondary exploit for code execution.
Exploitation of this vulnerability is possible by combining it with a secondary vulnerability to achieve a full sandbox bypass. Remote attackers who successfully exploit this vulnerability (and the secondary vulnerability) will be able to execute code on the vulnerable system with the same rights as the currently logged on user.
Disable Java in browsers.
