-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat JBoss Web Server 2.0.1 update Advisory ID: RHSA-2013:1013-01 Product: Red Hat JBoss Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1013.html Issue date: 2013-07-03 CVE Names: CVE-2012-3499 CVE-2012-3544 CVE-2012-4558 CVE-2013-0166 CVE-2013-0169 CVE-2013-2067 CVE-2013-2071 ===================================================================== 1. Summary: Red Hat JBoss Web Server 2.0.1, which fixes multiple security issues and several bugs, is now available from the Red Hat Customer Portal for Red Hat Enterprise Linux 5 and 6, Solaris, and Microsoft Windows. 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. Description: Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. This release serves as a replacement for Red Hat JBoss Web Server 2.0.0, and includes several bug fixes. Refer to the Red Hat JBoss Web Server 2.0.1 Release Notes for information on the most significant of these changes, available shortly from https://access.redhat.com/site/documentation/ The following security issues are also fixed with this release: Cross-site scripting (XSS) flaws were found in the Apache HTTP Server mod_proxy_balancer module's manager web interface. If a remote attacker could trick a user, who was logged into the manager web interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's manager interface session. (CVE-2012-4558) Cross-site scripting (XSS) flaws were found in the Apache HTTP Server mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp modules. An attacker could possibly use these flaws to perform XSS attacks if they were able to make the victim's browser generate an HTTP request with a specially-crafted Host header. (CVE-2012-3499) A NULL pointer dereference flaw was found in the OCSP response verification in OpenSSL. A malicious OCSP server could use this flaw to crash applications performing OCSP verification by sending a specially-crafted response. (CVE-2013-0166) It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169) Note: CVE-2013-0166 and CVE-2013-0169 were only corrected in the packages for Solaris and Windows. Updates for Red Hat Enterprise Linux can be downloaded from the Red Hat Network. A session fixation flaw was found in the Tomcat FormAuthenticator module. During a narrow window of time, if a remote attacker sent requests while a user was logging in, it could possibly result in the attacker's requests being processed as if they were sent by the user. (CVE-2013-2067) A denial of service flaw was found in the way the Tomcat chunked transfer encoding input filter processed CRLF sequences. A remote attacker could use this flaw to send an excessively long request, consuming network bandwidth, CPU, and memory on the Tomcat server. Chunked transfer encoding is enabled by default. (CVE-2012-3544) A flaw was found in the way the Tomcat 7 asynchronous context implementation performed request management in certain circumstances. If an application used AsyncListeners and threw RuntimeExceptions, Tomcat could send a reply that contains information from a different user's request, possibly leading to the disclosure of sensitive information. This issue only affected Tomcat 7. (CVE-2013-2071) Warning: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). All users of Red Hat JBoss Web Server 2.0.0 as provided from the Red Hat Customer Portal are advised to upgrade to Red Hat JBoss Web Server 2.0.1, which corrects these issues. 3. Solution: 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 Red Hat JBoss Web Server installation (including all applications and configuration files). 4.
