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. Apache Tomcat Calculates the hash value of the form parameter without restricting the assumption of hash collision. (CPU Resource consumption ) There is a vulnerability that becomes a condition.A third party can send a large amount of crafted parameters to disrupt service operation. (CPU Resource consumption ) There is a possibility of being put into a state. Apache Tomcat is prone to a denial-of-service vulnerability. An attacker can exploit this issue by sending specially crafted forms in HTTP POST requests. ---------------------------------------------------------------------- Secunia is hiring!

A flaw was found in the way JBoss Web handled UTF-8 surrogate pair characters. If JBoss Web was hosting an application with UTF-8 character encoding enabled, or that included user-supplied UTF-8 strings in a response, a remote attacker could use this flaw to cause a denial of service (infinite loop) on the JBoss Web server. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: tomcat5 security and bug fix update Advisory ID: RHSA-2012:0680-01 Product: JBoss Enterprise Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0680.html Issue date: 2012-05-21 CVE Names: CVE-2011-1184 CVE-2011-2204 CVE-2011-2526 CVE-2011-3190 CVE-2011-4858 CVE-2011-5062 CVE-2011-5063 CVE-2011-5064 CVE-2012-0022 ===================================================================== 1. Summary: Updated tomcat5 packages that fix multiple security issues and two 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 for the Java Servlet and JavaServer Pages (JSP) technologies. 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 includes bug fixes as documented in JBPAPP-4873 and JBPAPP-6133. It also resolves the following security issues: 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, 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) It was found that 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) It was found that 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 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 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. Users of Tomcat should upgrade to these updated packages, which resolve these issues. Tomcat must be restarted for this update to take effect. 4.

Software Description: - tomcat6: Servlet and JSP engine Details: It was discovered that Tomcat incorrectly performed certain caching and recycling operations. This issue only applied to Ubuntu 11.10. (CVE-2011-4858) It was discovered that Tomcat incorrectly handled parameters. (CVE-2012-0022) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: libtomcat6-java 6.0.32-5ubuntu1.2 Ubuntu 11.04: libtomcat6-java 6.0.28-10ubuntu2.3 Ubuntu 10.10: libtomcat6-java 6.0.28-2ubuntu1.6 Ubuntu 10.04 LTS: libtomcat6-java 6.0.24-2ubuntu1.10 In general, a standard system update will make all the necessary changes. (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. The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files)
