CVE-2016-6816

TITLE

Apache Tomcat Updates for multiple vulnerabilities

DESCRIPTION

The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 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 and/or obtain sensitive information from requests other then their own. The Apache Software Foundation From Apache Tomcat Updates for the following multiple vulnerabilities have been released: * * HTTP Response falsification (CVE-2016-6816) * * Service operation interruption (DoS) (CVE-2016-6817) * * Arbitrary code execution (CVE-2016-8735)Expected impact varies depending on each vulnerability, but information leakage, service operation interruption (DoS) May be affected by arbitrary code execution. Apache Tomcat is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks. Apache Tomcat 9.0.0.M1 through 9.0.0.M11, 8.5.0 through 8.5.6, 8.0.0.RC1 through 8.0.38, 7.0.0 through 7.0.72 and 6.0.0 through 6.0.47 are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Web Server 3.1.0 security and enhancement update Advisory ID: RHSA-2017:0455-01 Product: Red Hat JBoss Web Server Advisory URL: https://access.redhat.com/errata/RHSA-2017:0455 Issue date: 2015-11-12 Updated on: 2017-03-07 CVE Names: CVE-2016-0762 CVE-2016-1240 CVE-2016-3092 CVE-2016-5018 CVE-2016-6325 CVE-2016-6794 CVE-2016-6796 CVE-2016-6797 CVE-2016-6816 CVE-2016-8735 CVE-2016-8745 ===================================================================== 1. Summary: An update is now available for Red Hat JBoss Web Server 3 for RHEL 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 Web Server 3.1 for RHEL 6 - i386, noarch, ppc64, x86_64 3. Description: Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. This release of Red Hat JBoss Web Server 3.1.0 serves as a replacement for Red Hat JBoss Web Server 3.0.3, and includes enhancements. Security Fix(es): * It was reported that the Tomcat init script performed unsafe file handling, which could result in local privilege escalation. (CVE-2016-1240) * It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. (CVE-2016-6325) * The JmxRemoteLifecycleListener was not updated to take account of Oracle's fix for CVE-2016-3427. JMXRemoteLifecycleListener is only included in EWS 2.x and JWS 3.x source distributions. If you deploy a Tomcat instance built from source, using the EWS 2.x, or JWS 3.x distributions, an attacker could use this flaw to launch a remote code execution attack on your deployed instance. (CVE-2016-8735) * 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-2016-6816) * A bug was discovered in the error handling of the send file code for the NIO HTTP connector. This led to the current Processor object being added to the Processor cache multiple times allowing information leakage between requests including, and not limited to, session ID and the response body. (CVE-2016-8745) * The Realm implementations did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder. (CVE-2016-0762) * It was discovered that a malicious web application could bypass a configured SecurityManager via a Tomcat utility method that was accessible to web applications. (CVE-2016-5018) * It was discovered that when a SecurityManager is configured Tomcat's system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible. (CVE-2016-6794) * It was discovered that a malicious web application could bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796) * It was discovered that it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. (CVE-2016-6797) The CVE-2016-6325 issue was discovered by Red Hat Product Security. Enhancement(s): This enhancement update adds the Red Hat JBoss Web Server 3.1.0 packages to Red Hat Enterprise Linux 6. These packages provide a number of enhancements over the previous version of Red Hat JBoss Web Server. (JIRA#JWS-267) Users of Red Hat JBoss Web Server are advised to upgrade to these updated packages, which add this enhancement. 4. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the updated packages, the httpd daemon will be restarted automatically. 5.

This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-5018) It was discovered that Tomcat did not protect applications from untrusted data in the HTTP_PROXY environment variable. A remote attacker could possibly use this issue to redirect outbound traffic to an arbitrary proxy server. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-5388) It was discovered that Tomcat incorrectly controlled reading system properties. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-6816) Pierre Ernst discovered that the Tomcat JmxRemoteLifecycleListener did not implement a recommended fix. A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2016-8745) Paul Szabo discovered that the Tomcat package incorrectly handled upgrades and removals. A local attacker could possibly use this issue to obtain root privileges. (CVE-2016-9774, CVE-2016-9775) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: libtomcat7-java 7.0.52-1ubuntu0.9 tomcat7 7.0.52-1ubuntu0.9 Ubuntu 12.04 LTS: libtomcat6-java 6.0.35-1ubuntu3.10 tomcat6 6.0.35-1ubuntu3.10 In general, a standard system update will make all the necessary changes.
