TITLE

Expat of expat/lib/xmlparse.c Service disruption in ( Memory consumption ) Vulnerabilities

DESCRIPTION

Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. The Expat library is prone to multiple denial-of-service vulnerabilities because it fails to properly handle crafted XML data. Exploiting these issues allows remote attackers to cause denial-of-service conditions in the context of an application using the vulnerable XML parsing library. Expat versions prior to 2.1.0 are vulnerable. Expat is a C language-based XML parser library developed by American software developer Jim Clark, which uses a stream-oriented parser. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat JBoss Web Server 2.1.0 security update Advisory ID: RHSA-2016:0062-01 Product: Red Hat JBoss Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0062.html Issue date: 2016-01-21 CVE Names: CVE-2012-0876 CVE-2012-1148 CVE-2013-5704 CVE-2015-3183 ===================================================================== 1. Summary: An update for Red Hat JBoss Web Server 2.1.0 that fixes four security issues is now available from the Red Hat Customer Portal. Red Hat Product Security 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. Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. (CVE-2015-3183) A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially-crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. (CVE-2012-0876) A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted. (CVE-2012-1148) A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) All users of Red Hat JBoss Web Server 2.1.0 as provided from the Red Hat Customer Portal are advised to apply this update. The Red Hat JBoss Web Server process must be restarted for the update to take effect. 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.
