-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Web Server 2.1.2 security update for Tomcat 7 Advisory ID: RHSA-2016:2807-01 Product: Red Hat JBoss Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2807.html Issue date: 2016-11-17 CVE Names: CVE-2015-5346 CVE-2015-5351 CVE-2016-0706 CVE-2016-0714 CVE-2016-0763 CVE-2016-3092 ===================================================================== 1. Summary: An update is now available for Red Hat JBoss Enterprise Web Server 2 for RHEL 6 and Red Hat JBoss Enterprise Web Server 2 for RHEL 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. 2. Relevant releases/architectures: Red Hat JBoss Enterprise Web Server 2 for RHEL 6 Server - noarch Red Hat JBoss Enterprise Web Server 2 for RHEL 7 Server - noarch 3. Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. This release of Red Hat JBoss Web Server 2.1.2 serves as a replacement for Red Hat JBoss Web Server 2.1.1. It contains security fixes for the Tomcat 7 component. Only users of the Tomcat 7 component in JBoss Web Server need to apply the fixes delivered in this release. Security Fix(es): * A CSRF flaw was found in Tomcat's the index pages for the Manager and Host Manager applications. These applications included a valid CSRF token when issuing a redirect as a result of an unauthenticated request to the root of the web application. This token could then be used by an attacker to perform a CSRF attack. (CVE-2015-5351) * It was found that several Tomcat session persistence mechanisms could allow a remote, authenticated user to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that placed a crafted object in a session. (CVE-2016-0714) * A security manager bypass flaw was found in Tomcat that could allow remote, authenticated users to access arbitrary application data, potentially resulting in a denial of service. (CVE-2016-0763) * A denial of service vulnerability was identified in Commons FileUpload that occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file if the boundary was the typical tens of bytes long. (CVE-2016-3092) * A session fixation flaw was found in the way Tomcat recycled the requestedSessionSSL field. If at least one web application was configured to use the SSL session ID as the HTTP session ID, an attacker could reuse a previously used session ID for further requests. (CVE-2015-5346) * It was found that Tomcat allowed the StatusManagerServlet to be loaded by a web application when a security manager was configured. This allowed a web application to list all deployed web applications and expose sensitive information such as session IDs. (CVE-2016-0706) 4.
