TITLE

Apache Log4j CVE-2017-5645 Remote Code Execution Vulnerability

DESCRIPTION

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. Apache Log4j is prone to remote code-execution vulnerability. Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the affected application. Failed exploits will result in denial-of-service conditions. Apache Log4j 2.0-alpha1 through 2.8.1 are vulnerable. Apache Log4j is a Java-based open source logging tool developed by the Apache Software Foundation. The purpose of this text-only errata is to inform you about the security issues fixed in this release.

(CVE-2017-7525) Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525. (CVE-2017-5645) * It was found that XStream contains a vulnerability that allows a maliciously crafted file to be parsed successfully which could cause an application crash. The crash occurs if the file that is being fed into XStream input stream contains an instances of the primitive type 'void'. An attacker could use this flaw to create a denial of service on the target system. (CVE-2017-7957) 3. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update; after installing the update, restart the server by starting the JBoss Application Server process. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: log4j security update Advisory ID: RHSA-2017:2423-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2423 Issue date: 2017-08-07 CVE Names: CVE-2017-5645 ===================================================================== 1.

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 of Red Hat JBoss Web Server 3.1 Service Pack 1 serves as a replacement for Red Hat JBoss Web Server 3.1, and includes bug fixes, which are documented in the Release Notes document linked to in the References. (CVE-2017-5645) * A vulnerability was discovered in tomcat's handling of pipelined requests when "Sendfile" was used. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647) * A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of the custom error page. (CVE-2017-5664) * A vulnerability was discovered in tomcat. When running an untrusted application under a SecurityManager it was possible, under some circumstances, for that application to retain references to the request or response objects and thereby access and/or modify information associated with another web application. (CVE-2017-5648) 3. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). The References section of this erratum contains a download link (you must log in to download the update).
