Description

Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server.

Security Fix(es):

• A deserialization flaw was discovered in jackson-databind which could allow an unauthenticated user to perform code execution by sending maliciously crafted input to the readValue method of the ObjectMapper. (CVE-2017-7525)
  
• It was found that use of a JMS ObjectMessage does not safely handle user-supplied data when deserializing objects. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the JMS ObjectMessage. (CVE-2016-4978)
