CVE-2012-1721

Vulnerabilidad no especificada en el componente Java Runtime Enviroment (JRE) en Oracle Java SE v7 actualización 4 y anteriores, y v6 actualización 32 y anteriores, permite a atacantes remotos afectar la confidencialidad, integridad y disponibilidad a través de vectores relacionados con el despliegue, una vulnerabilidad diferente de CVE-2012-1722.

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 "<all-permissions/>" 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.

This update corrects several security vulnerabilities in the IBM Java Runtime Environment shipped as part of Red Hat Network Satellite Server 5.5. In a typical operating environment, these are of low security risk as the runtime is not used on untrusted applets. Several flaws were fixed in the IBM Java 2 Runtime Environment.
