RHSA-2017:1412: Moderate: eap7-jboss-ec2-eap security update

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).<br>With this update, the eap7-jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 7.0.6.<br>Refer to the JBoss Enterprise Application Platform 7.0.6 Release Notes, linked to in the References section, for information on the most significant bug fixes and enhancements included in this release.<br>Security Fix(es):<br><li> It was discovered that under certain conditions RESTEasy could be forced to parse a request with YamlProvider, resulting in unmarshalling of potentially untrusted data. An attacker could possibly use this flaw execute arbitrary code with the permissions of the application using RESTEasy. (CVE-2016-9606)</li> <li> It was found that the log file viewer in Red Hat JBoss Enterprise Application 6 and 7 allows arbitrary file read to authenticated user via path traversal. (CVE-2017-2595)</li> <li> It was discovered that the code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other than their own. (CVE-2017-2666)</li> <li> It was found that with non-clean TCP close, Websocket server gets into infinite loop on every IO thread, effectively causing DoS. (CVE-2017-2670)</li> Red Hat would like to thank Moritz Bechler (AgNO3 GmbH &amp; Co. KG) for reporting CVE-2016-9606 and Gregory Ramsperger and Ryan Moak for reporting CVE-2017-2670. The CVE-2017-2666 issue was discovered by Radim Hatlapatka (Red Hat).
