-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle Java. User interaction is required to
exploit this vulnerability in that the target must visit a malicious
page or open a malicious file.

The specific flaw exists within the way Java webstart parses certain
properties from the jnlp file. Due to insufficient quote escaping it is
possible to supply additional command line parameters to the java
process. By crafting such parameters, an attacker can execute remote
code under the context of the user running the process.

-- Vendor Response:
Oracle has issued an update to correct this vulnerability. More
