TITLE

Apache Portable Runtime Used in products such as libraries apr_fnmatch.c and fnmatch.c Service disruption in (CPU And memory consumption ) Vulnerabilities

DESCRIPTION

Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd. The purpose of APR (Apache portable Run-time libraries, Apache portable runtime library) is the same as its name. It mainly provides an underlying support interface library for upper-level applications that can be used across multiple operating system platforms. NetBSD is a free and open source Unix-like operating system developed by the NetBSD Foundation. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: JBoss Enterprise Web Server 1.0.2 update Advisory ID: RHSA-2011:0896-01 Product: JBoss Enterprise Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0896.html Issue date: 2011-06-22 CVE Names: CVE-2008-7270 CVE-2009-3245 CVE-2009-3560 CVE-2009-3720 CVE-2009-3767 CVE-2010-1157 CVE-2010-1452 CVE-2010-1623 CVE-2010-2068 CVE-2010-3718 CVE-2010-4172 CVE-2010-4180 CVE-2011-0013 CVE-2011-0419 ===================================================================== 1. Summary: JBoss Enterprise Web Server 1.0.2 is now available from the Red Hat Customer Portal for Red Hat Enterprise Linux 4, 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: JBoss Enterprise Web Server is a fully-integrated and certified set of components for hosting Java web applications. This is the first release of JBoss Enterprise Web Server for Red Hat Enterprise Linux 6. For Red Hat Enterprise Linux 4 and 5, Solaris, and Microsoft Windows, this release serves as a replacement for JBoss Enterprise Web Server 1.0.1, and includes a number of bug fixes. Refer to the Release Notes, linked in the References, for more information. This update corrects security flaws in the following components: tomcat6: A cross-site scripting (XSS) flaw was found in the Manager application, used for managing web applications on Apache Tomcat. If a remote attacker could trick a user who is logged into the Manager application into visiting a specially-crafted URL, the attacker could perform Manager application tasks with the privileges of the logged in user. (CVE-2010-4172) tomcat5 and tomcat6: It was found that web applications could modify the location of the Apache Tomcat host's work directory. As web applications deployed on Tomcat have read and write access to this directory, a malicious web application could use this flaw to trick Tomcat into giving it read and write access to an arbitrary directory on the file system. (CVE-2010-3718) A second cross-site scripting (XSS) flaw was found in the Manager application. A malicious web application could use this flaw to conduct an XSS attack, leading to arbitrary web script execution with the privileges of victims who are logged into and viewing Manager application web pages. (CVE-2011-0013) A possible minor information leak was found in the way Apache Tomcat generated HTTP BASIC and DIGEST authentication requests. For configurations where a realm name was not specified and Tomcat was accessed via a proxy, the default generated realm contained the hostname and port used by the proxy to send requests to the Tomcat server. (CVE-2010-1157) httpd: A flaw was found in the way the mod_dav module of the Apache HTTP Server handled certain requests. If a remote attacker were to send a carefully crafted request to the server, it could cause the httpd child process to crash. (CVE-2010-1452) A flaw was discovered in the way the mod_proxy_http module of the Apache HTTP Server handled the timeouts of requests forwarded by a reverse proxy to the back-end server. In some configurations, the proxy could return a response intended for another user under certain timeout conditions, possibly leading to information disclosure. Note: This issue only affected httpd running on the Windows operating system. (CVE-2010-2068) apr: It was found that the apr_fnmatch() function used an unconstrained recursion when processing patterns with the '*' wildcard. An attacker could use this flaw to cause an application using this function, which also accepted untrusted input as a pattern for matching (such as an httpd server using the mod_autoindex module), to exhaust all stack memory or use an excessive amount of CPU time when performing matching. (CVE-2011-0419) apr-util: It was found that certain input could cause the apr-util library to allocate more memory than intended in the apr_brigade_split_line() function. An attacker able to provide input in small chunks to an application using the apr-util library (such as httpd) could possibly use this flaw to trigger high memory consumption. (CVE-2010-1623) The following flaws were corrected in the packages for Solaris and Windows. Updates for Red Hat Enterprise Linux can be downloaded from the Red Hat Network. Multiple flaws in OpenSSL, which could possibly cause a crash, code execution, or a change of session parameters, have been corrected. (CVE-2009-3245, CVE-2010-4180, CVE-2008-7270) Two denial of service flaws were corrected in Expat. (CVE-2009-3560, CVE-2009-3720) An X.509 certificate verification flaw was corrected in OpenLDAP. (CVE-2009-3767) More information about these flaws is available from the CVE links in the References. 3. Solution: All users of JBoss Enterprise Web Server 1.0.1 as provided from the Red Hat Customer Portal are advised to upgrade to JBoss Enterprise Web Server 1.0.2, which corrects these issues. The References section of this erratum contains a download link (you must log in to download the update). Before installing the update, backup your existing JBoss Enterprise Web Server installation (including all applications and configuration files). Apache Tomcat and the Apache HTTP Server must be restarted for the update to take effect. 4.
