Synopsis

The remote Red Hat host is missing one or more security updates for eap7-jboss-ec2-eap.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1837 advisory.

The eap7-jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

With this update, the eap7-jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 7.0.7.

Refer to the JBoss Enterprise Application Platform 7.0.7 Release Notes, linked to in the References section, for information on the most significant bug fixes and enhancements included in this release.

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)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL eap7-jboss-ec2-eap package based on the guidance in RHSA-2017:1837.
