  • Overview
  • Updated Packages

Synopsis

Important: eap7-jboss-ec2-eap security update

Type/Severity

Security Advisory: Important

Topic

An update for eap7-jboss-ec2-eap is now available for Red Hat JBoss Enterprise Application Platform 7.1 for Red Hat Enterprise Linux 6 and Red Hat JBoss Enterprise Application Platform 7.1 for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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 7.1.

Refer to the JBoss Enterprise Application Platform 7.1 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 Denial of Service can be caused when a long request is sent to EAP 7. (CVE-2016-7046)
  • The jboss init script unsafe file handling resulting in local privilege escalation. (CVE-2016-8656)
  • A deserialization vulnerability via readValue method of ObjectMapper which allows arbitrary code execution. (CVE-2017-7525)
  • JMSObjectMessage deserializes potentially malicious objects allowing Remote Code Execution. (CVE-2016-4978)
  • Undertow is vulnerable to the injection of arbitrary HTTP headers, and also response splitting. (CVE-2016-4993)
  • The domain controller will not propagate its administrative RBAC configuration to some slaves leading to escalate their privileges. (CVE-2016-5406)
  • Internal IP address disclosed on redirect when request header Host field is not set. (CVE-2016-6311)
  • Potential EAP resource starvation DOS attack via GET requests for server log files. (CVE-2016-8627)
  • Inefficient Header Cache could cause denial of service. (CVE-2016-9589)
  • The log file viewer allows arbitrary file read to authenticated user via path traversal. (CVE-2017-2595)
  • HTTP Request smuggling vulnerability due to permitting invalid characters in HTTP requests. (CVE-2017-2666)
  • Websocket non clean close can cause IO thread to get stuck in a loop. (CVE-2017-2670)
  • Privilege escalation with security manager's reflective permissions when granted to Hibernate Validator. (CVE-2017-7536)
  • Potential http request smuggling as Undertow parses the http headers with unusual whitespaces. (CVE-2017-7559)
  • Properties based files of the management and the application realm are world readable allowing access to users and roles information to all the users logged in to the system. (CVE-2017-12167)
  • RBAC configuration allows users with a Monitor role to view the sensitive information. (CVE-2016-7061)
  • Improper whitespace parsing leading to potential HTTP request smuggling. (CVE-2017-12165)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525; Calum Hutton (NCC Group) and Mikhail Egorov (Odin) for reporting CVE-2016-4993; Luca Bueti for reporting CVE-2016-6311; Gabriel Lavoie (Halogen Software) for reporting CVE-2016-9589; and Gregory Ramsperger and Ryan Moak for reporting CVE-2017-2670.
