Summary
Red Hat Security Advisory: Red Hat JBoss Enterprise Application Platform 6.4.19 security update
Severity
Important
Notes
Topic: An update is now available for Red Hat JBoss Enterprise Application Platform. 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. [Updated 5th February 2018] Previously, this erratum was marked as a security update for EAP 6.4.18. This was incorrect; the erratum is a security update for EAP 6.4.19.The erratum has been modified to reflect this.
Details: Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server. This release of Red Hat JBoss Enterprise Application Platform 6.4.19 serves as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.18, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es): * It was found that when Artemis and HornetQ are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError. (CVE-2017-12174) * A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution. (CVE-2017-12617) * A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10.Final-redhat-1, reads from an empty buffer. An attacker could use this flaw to cause denial of service via high CPU caused by an infinite loop. (CVE-2018-1041) The CVE-2017-12174 issue was discovered by Masafumi Miura (Red Hat).
