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. 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. 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. 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.

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. 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.

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. Description: JBoss Enterprise Portal Platform is the open source implementation of the Java EE suite of services and Portal services running atop JBoss Enterprise Application Platform. It comprises a set of offerings for enterprise customers who are looking for pre-configured profiles of JBoss Enterprise Middleware components that have been tested and certified together to provide an integrated experience. This JBoss Enterprise Portal Platform 4.3 CP07 release serves as a replacement for JBoss Enterprise Portal Platform 4.3 CP06. The following security fixes are also included: JBoss Seam 2 did not properly block access to JBoss Expression Language (EL) constructs in page exception handling, allowing arbitrary Java methods to be executed. Note: A properly configured and enabled Java Security Manager would prevent exploitation of this flaw. (CVE-2011-1484) Note: If you have created custom applications that are packaged with a copy of the JBoss Seam 2 library, those applications must be rebuilt with the updated jboss-seam.jar file provided by this update. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064) The invoker servlets, deployed by default via httpha-invoker, only performed access control on the HTTP GET and POST methods, allowing remote attackers to make unauthenticated requests by using different HTTP methods. Due to the second layer of authentication provided by a security interceptor, this issue is not exploitable on default installations unless an administrator has misconfigured the security interceptor or disabled it. Note that if you have created custom applications that are packaged with a copy of the JBoss Seam 2 library, those applications must be rebuilt with the updated jboss-seam.jar file provided by this update.

Description: JBoss Operations Network (JBoss ON) is a middleware management solution that provides a single point of control to deploy, manage, and monitor JBoss Enterprise Middleware, applications, and services. The Release Notes will be available shortly from https://docs.redhat.com/docs/en-US/index.html The following security issues are also fixed with this release: JBoss ON did not properly verify security tokens, allowing an unapproved agent to connect as an approved agent. As a result, the attacker could retrieve sensitive data about the server the hijacked agent was running on, including JMX credentials. (CVE-2012-0052) JBoss ON sometimes allowed agent registration to succeed when the registration request did not include a security token. This is a feature designed to add convenience. A remote attacker could use this flaw to spoof the identity of an approved agent and pass a null security token, allowing them to hijack the approved agent's session, and steal its security token. As a result, the attacker could retrieve sensitive data about the server the hijacked agent was running on, including JMX credentials. (CVE-2012-0062) A flaw was found in the way LDAP (Lightweight Directory Access Protocol) authentication was handled. If the LDAP bind account credentials became invalid, subsequent log in attempts with any password for user accounts created via LDAP were successful. (CVE-2011-4858) It was found that after installing the remote client (by extracting rhq-remoting-cli-[version].zip), its root directory had world read, write, and execute permissions. This allowed the attributes of the child directories and their files to be modified. A local attacker could use this flaw to steal the JBoss ON credentials of a user running the remote client, or trick them into running arbitrary code. The remote client is typically used by privileged JBoss ON users. Bugs fixed (http://bugzilla.redhat.com/): 750521 - CVE-2011-4858 tomcat: hash table collisions CPU usage DoS (oCERT-2011-003) 772514 - CVE-2012-0032 JON CLI: world-writable root directory 781964 - CVE-2012-0052 JON: Unapproved agents can connect using the name of an existing approved agent 783008 - CVE-2012-0062 JON: Unapproved agents can hijack an approved agent's endpoint by using a null security token 799789 - CVE-2012-1100 JON: LDAP authentication allows any user access if bind credentials are bad 5
