-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: jboss-ec2-eap security, bug fix, and enhancement update Advisory ID: RHSA-2017:2638-01 Product: Red Hat JBoss Enterprise Application Platform Advisory URL: https://access.redhat.com/errata/RHSA-2017:2638 Issue date: 2017-09-05 CVE Names: CVE-2017-5645 CVE-2017-5664 CVE-2017-7525 ===================================================================== 1. Summary: An update for jboss-ec2-eap is now available for Red Hat JBoss Enterprise Application Platform 6.4 for Red Hat Enterprise Linux 6. 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. 2. Relevant releases/architectures: Red Hat JBoss Enterprise Application Platform 6.4 for RHEL 6 Server - noarch 3. Description: The 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 jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 6.4.17. 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. (CVE-2017-7525) Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525. 4.
