Zero Day Initiative Advisory 12-189

Zero Day Initiative Advisory 12-189 - 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 because it is possible to change system properties through trusted JNLP files. If a JNLP file requests "" and only references signed, trusted JAR files, it can set all System properties. By referencing a trusted JNLP file from an untrusted one it is possible to change System Properties that can lead to remote code execution under the context of the current user.
