TITLE

Apache Tomcat Vulnerability that could bypass the security manager limitation in the default servlet

DESCRIPTION

java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue. In Apache Tomcat 6.x before 6.0.55, it was possible to craft a malformed chunk as part of a chunked request that caused Tomcat to read part of the request body as a new request (CVE-2014-0227). The verification of md5 checksums and GPG signatures is performed automatically for you.

Summary: Updated tomcat packages that fix three security issues are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch Red Hat Enterprise Linux Client Optional (v. 7) - noarch Red Hat Enterprise Linux ComputeNode (v. 7) - noarch Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch Red Hat Enterprise Linux Server (v. 7) - noarch Red Hat Enterprise Linux Server Optional (v. 7) - noarch Red Hat Enterprise Linux Workstation (v. 7) - noarch Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch 3. Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. It was discovered that Apache Tomcat did not limit the length of chunk sizes when using chunked transfer encoding. A remote attacker could use this flaw to perform a denial of service attack against Tomcat by streaming an unlimited quantity of data, leading to excessive consumption of server resources. (CVE-2014-0075) It was found that Apache Tomcat did not check for overflowing values when parsing request content length headers. A remote attacker could use this flaw to perform an HTTP request smuggling attack on a Tomcat server located behind a reverse proxy that processed the content length header correctly. (CVE-2014-0099) It was found that the org.apache.catalina.servlets.DefaultServlet implementation in Apache Tomcat allowed the definition of XML External Entities (XXEs) in provided XSLTs. A malicious application could use this to circumvent intended security restrictions to disclose sensitive information. (CVE-2014-0096) The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product Security. All Tomcat 7 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Tomcat must be restarted for this update to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.

Software Description: - tomcat7: Servlet and JSP engine - tomcat6: Servlet and JSP engine Details: David Jorm discovered that Tomcat incorrectly handled certain requests submitted using chunked transfer encoding. (CVE-2014-0075) It was discovered that Tomcat did not properly restrict XSLT stylesheets. (CVE-2014-0096) It was discovered that Tomcat incorrectly handled certain Content-Length headers. (CVE-2014-0099) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: libtomcat7-java 7.0.52-1ubuntu0.1 Ubuntu 12.04 LTS: libtomcat6-java 6.0.35-1ubuntu3.5 Ubuntu 10.04 LTS: libtomcat6-java 6.0.24-2ubuntu1.16 In general, a standard system update will make all the necessary changes. (CVE-2014-0096) It was found that, in certain circumstances, it was possible for a malicious web application to replace the XML parsers used by JBoss Web to process XSLTs for the default servlet, JSP documents, tag library descriptors (TLDs), and tag plug-in configuration files. The injected XML parser(s) could then bypass the limits imposed on XML external entities and/or gain access to the XML files processed for other web applications deployed on the same JBoss Web instance. Solution: The References section of this erratum contains a download link (you must log in to download the update). Description: Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. This update also fixes the following bug: The tomcat6-lib-6.0.37-19_patch_04.ep6.el5 package, provided as a dependency of Red Hat JBoss Web Server 2.0.1, included a build of commons-dbcp.jar that used an incorrect java package name, causing applications using this dependency to not function properly. With this update, the java package name has been corrected. This update also fixes the following bugs: * The patch that resolved the CVE-2014-0050 issue contained redundant code. This update removes the redundant code. (BZ#1094528) * The patch that resolved the CVE-2013-4322 issue contained an invalid check that triggered a java.io.EOFException while reading trailer headers for chunked requests. This update fixes the check and the aforementioned exception is no longer triggered in the described scenario. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201412-29 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Apache Tomcat: Multiple vulnerabilities Date: December 15, 2014 Bugs: #442014, #469434, #500600, #511762, #517630, #519590 ID: 201412-29 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Apache Tomcat, the worst of which may result in Denial of Service.
