Red Hat Security Advisory 2017-2638-01 - The jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services Elastic Compute Cloud. With this update, the jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 6.4.17. Security Fix: It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application.

3. Description:
The jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise

Security Fix(es):
* It was found that when using remote logging with log4j socket server the
log4j server would deserialize any log event received via TCP or UDP. An
attacker could use this flaw to send a specially crafted log event that,
during deserialization, would execute arbitrary code in the context of the
logger application. (CVE-2017-5645)
* A vulnerability was discovered in the error page mechanism in Tomcat's
DefaultServlet implementation. A crafted HTTP request could cause undesired
side effects, possibly including the removal or replacement of the custom
error page. (CVE-2017-5664)
* A deserialization flaw was discovered in the jackson-databind which could
allow an unauthenticated user to perform code execution by sending the
maliciously crafted input to the readValue method of the ObjectMapper.
