The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Important: tomcat6 security update Advisory ID: RHSA-2013:0623-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2013:0623.html Issue date: 2013-03-11 CVE Names: CVE-2012-3546 CVE-2012-4534 CVE-2012-5885 CVE-2012-5886 CVE-2012-5887 ==================================================================== 1. Summary: Updated tomcat6 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important 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 Desktop Optional (v. 6) - noarch Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch Red Hat Enterprise Linux Server (v. 6) - noarch Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation (v. 6) - noarch Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch 3. Description: Apache Tomcat is a servlet container. It was found that when an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending "/j_security_check" to the end of a URL. A remote attacker with anauthenticated session on an affected application could use this flaw to circumvent authorization controls, and thereby access resources not permitted by the roles associated with their authenticated session. (CVE-2012-3546) A flaw was found in the way Tomcat handled sendfile operations when using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote attacker could use this flaw to cause a denial of service (infinite loop). The HTTP blocking IO (BIO) connector, which is not vulnerable to this issue, is used by default in Red Hat Enterprise Linux 6. (CVE-2012-4534) Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887) Users of Tomcat should upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect. 4.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: tomcat6 security and bug fix update Advisory ID: RHSA-2011:1780-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2011:1780.html Issue date: 2011-12-05 CVE Names: CVE-2011-1184 CVE-2011-2204 CVE-2011-2526 CVE-2011-3190 ==================================================================== 1. Summary: Updated tomcat6 packages that fix several security issues and one bug are now available for Red Hat Enterprise Linux 6. 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 Desktop Optional (v. 6) - noarch Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch Red Hat Enterprise Linux Server (v. 6) - noarch Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation (v. 6) - noarch Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch 3. Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. APR (Apache Portable Runtime) as mentioned in the CVE-2011-3190 and CVE-2011-2526 descriptions does not refer to APR provided by the apr packages. It refers to the implementation of APR provided by the Tomcat Native library, which provides support for using APR with Tomcat. This library is not shippedwith Red Hat Enterprise Linux 6. This update includes fixes for users who have elected to use APR with Tomcat by taking the Tomcat Native library from a different product. Such a configuration is not supported by Red Hat, however. Multiple flaws were found in the way Tomcat handled HTTP DIGEST authentication. These flaws weakened the Tomcat HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. (CVE-2011-1184) A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor) and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ Protocol) connectors processed certain POST requests. An attacker could send a specially-crafted request that would cause the connector to treat the message body as a new request. This allows arbitrary AJP messages to be injected, possibly allowing an attacker to bypass a web application's authentication checks and gain access to information they would otherwise be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler) connector is used by default when the APR libraries are not present. The JK connector is not affected by this flaw. (CVE-2011-3190) A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception occurred when creating a new user with a JMX client, that user's password was logged to Tomcat log files. Note: By default, only administrators have access to such log files. (CVE-2011-2204) A flaw was found in the way Tomcat handled sendfile request attributes when using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web application running on a Tomcat instance could use this flaw to bypass security manager restrictions and gain access to files it would otherwise be unable to access, or possibly terminate the Java Virtual Machine (JVM). The HTTP blocking IO (BIO) connector, which is not vulnerable to this issue, is used by default in Red Hat Enterprise Linux 6. (CVE-2011-2526) Red Hatwould like to thank the Apache Tomcat project for reporting the CVE-2011-2526 issue. This update also fixes the following bug: * Previously, in certain cases, if "LANG=fr_FR" or "LANG=fr_FR.UTF-8" was set as an environment variable or in "/etc/sysconfig/tomcat6" on 64-bit PowerPC systems, Tomcat may have failed to start correctly. With this update, Tomcat works as expected when LANG is set to "fr_FR" or "fr_FR.UTF-8". (BZ#748807) Users of Tomcat should 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.

Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. A denial of service flaw was found in the way certain strings were converted to Double objects. A remote attacker could use this flaw to cause Tomcat to hang via a specially-crafted HTTP request. (CVE-2010-4476) A flaw was found in the Tomcat NIO (Non-Blocking I/O) connector. A remote attacker could use this flaw to cause a denial of service (out-of-memory condition) via a specially-crafted request containing a large NIO buffer size request value. (CVE-2011-0534) Thisupdate also fixes the following bug: * A bug in the "tomcat6" init script prevented additional Tomcat instances from starting. As well, running "service tomcat6 start" caused configuration options applied from "/etc/sysconfig/tomcat6" to be overwritten with those from "/etc/tomcat6/tomcat6.conf". With this update, multiple instances of Tomcat run as expected. (BZ#676922) Users of Tomcat should 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/kb/docs/DOC-11259 5.
