CVE-2011-4858

TITLE

Hash table implementations vulnerable to algorithmic complexity attacks

DESCRIPTION

Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. Some programming language implementations do not sufficiently randomize their hash functions or provide means to limit key collision attacks, which can be leveraged by an unauthenticated attacker to cause a denial-of-service (DoS) condition. Multiple Hitachi COBOL2002 products have security vulnerabilities that allow attackers to take control of target user systems. No detailed vulnerability details are provided at this time. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20566.www2.hp.com/portal/site/hpsc/public/kb/ docDisplay?docId=emr_na-c03716627 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c03716627 Version: 1 HPSBUX02860 SSRT101146 rev.1 - HP-UX Apache Running Tomcat Servlet Engine, Remote Denial of Service (DoS), Access Restriction Bypass, Unauthorized Modification and Other Vulnerabilities NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Summary: Updated tomcat6 packages that fix multiple security issues and three bugs are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 5 and 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: JBoss Enterprise Web Server 1.0 for RHEL 5 Server - noarch JBoss Enterprise Web Server 1.0 for RHEL 6 Server - noarch 3. Description: Apache Tomcat is a servlet container. JBoss Enterprise Web Server includes the Tomcat Native library, providing Apache Portable Runtime (APR) support for Tomcat. References in this text to APR refer to the Tomcat Native implementation, not any other apr package. This update fixes the JBPAPP-4873, JBPAPP-6133, and JBPAPP-6852 bugs. It also resolves the following security issues: Multiple 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, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064) 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 in the way Tomcat recycled objects that contain data from user requests (such as IP addresses and HTTP headers) when certain errors occurred. If a user sent a request that caused an error to be logged, Tomcat would return a reply to the next request (which could be sent by a different user) with data from the first user's request, leading to information disclosure. Under certain conditions, a remote attacker could leverage this flaw to hijack sessions. (CVE-2011-3375) The Java hashCode() method implementation was susceptible to predictable hash collisions. This update introduces a limit on the number of parameters processed per request to mitigate this issue. The default limit is 512 for parameters and 128 for headers. These defaults can be changed by setting the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties. (CVE-2011-4858) Tomcat did not handle large numbers of parameters and large parameter values efficiently. A remote attacker could make Tomcat use an excessive amount of CPU time by sending an HTTP request containing a large number of parameters or large parameter values. This update introduces limits on the number of parameters and headers processed per request to address this issue. Refer to the CVE-2011-4858 description for information about the org.apache.tomcat.util.http.Parameters.MAX_COUNT and org.apache.tomcat.util.http.MimeHeaders.MAX_COUNT system properties. (CVE-2012-0022) A flaw 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 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 NIO connector is used by default in JBoss Enterprise Web Server. (CVE-2011-2526) Red Hat would like to thank oCERT for reporting CVE-2011-4858, and the Apache Tomcat project for reporting CVE-2011-2526. oCERT acknowledges Julian Wälde and Alexander Klink as the original reporters of CVE-2011-4858. 4. Solution: Users of Tomcat should upgrade to these updated packages, which resolve these issues. Tomcat must be restarted for this update to take effect. 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/knowledge/articles/11258 5.
