Summary: JBoss Communications Platform 5.1.3, which fixes multiple security issues and various bugs, is now available from the Red Hat Customer Portal. 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. Description: The JBoss Communications Platform (JBCP) is an open source VoIP platform certified for JAIN SLEE 1.1 and SIP Servlets 1.1 compliance. JBCP serves as a high performance core for Service Delivery Platforms (SDPs) and IP Multimedia Subsystems (IMSs) by leveraging J2EE to enable the convergence of data and video in Next-Generation Intelligent Network (NGIN) applications. This JBoss Communications Platform 5.1.3 release serves as a replacement for JBoss Communications Platform 5.1.2, and includes various bug fixes. Refer to the JBoss Communications Platform 5.1.3 Release Notes for information on the most significant of these changes. 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: 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. (CVE-2011-4610) It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause JBoss Web to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit on the number of parameters and headers 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 in "server/$PROFILE/deploy/properties-service.xml". (CVE-2011-4858) It was found that JBoss Web did not handle large numbers of parameters and large parameter values efficiently. A remote attacker could make a JBoss Web server 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) Multiple flaws were found in the way JBoss Web handled HTTP DIGEST authentication. These flaws weakened the JBoss Web 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 JBoss Web handled sendfile request attributes when using the HTTP APR (Apache Portable Runtime) or NIO (Non-Blocking I/O) connector. A malicious web application running on a JBoss Web 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). (CVE-2011-2526) Red Hat would like to thank NTT OSSC for reporting CVE-2011-4610; 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. Warning: Before applying the update, back up your existing JBoss Communications Platform installation (including its databases, applications, configuration files, and so on). All users of JBoss Communications Platform 5.1.2 as provided from the Red Hat Customer Portal are advised to upgrade to JBoss Communications Platform 5.1.3. 3.
