TITLE

Apache Tomcat of java/org/apache/tomcat/util/buf/Ascii.java Integer overflow vulnerability

DESCRIPTION

Integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4, when operated behind a reverse proxy, allows remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: tomcat security update Advisory ID: RHSA-2014:0827-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0827.html Issue date: 2014-07-02 CVE Names: CVE-2014-0075 CVE-2014-0096 CVE-2014-0099 ===================================================================== 1. 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. (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. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1072776 - CVE-2014-0075 Tomcat/JBossWeb: Limited DoS in chunked transfer encoding input filter 1088342 - CVE-2014-0096 Tomcat/JBossWeb: XXE vulnerability via user supplied XSLTs 1102030 - CVE-2014-0099 Tomcat/JBossWeb: Request smuggling via malicious content length header 6.

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. For the oldstable distribution (wheezy), these problems have been fixed in version 6.0.45+dfsg-1~deb7u1. We recommend that you upgrade your tomcat6 packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20564.www2.hp.com/portal/site/hpsc/public/kb/ docDisplay?docId=emr_na-c04223376 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c04223376 Version: 1 HPSBUX03102 SSRT101681 rev.1 - HP-UX Apache Server Suite running Apache Tomcat or PHP, Remote Execution of Arbitrary Code and Denial of Service (DoS) and Other Vulnerabilities NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
