Vulnerabilities exist in Google App Engine, a cloud service for developing and hosting Web applications. The vulnerabilities could allow an attacker to escape from the Java Virtual Machine security sandbox and execute code on the underlying system.

Earlier this year, the company found vulnerabilities in Oracle’s Java Cloud Service.”]
