CVE-2017-5645

TITLE

Red Hat Security Advisory 2017-2810-01

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 a Java-based open source logging tool developed by the Apache Software Foundation. A code issue vulnerability exists in Apache Log4j 2.x versions prior to 2.8.2. An attacker could exploit this vulnerability to execute arbitrary code. (CVE-2017-5645) * A vulnerability was found in Jasypt that would allow an attacker to perform a timing attack on password hash comparison. (CVE-2014-9970) * It was found that an information disclosure flaw in Bouncy Castle could enable a local malicious application to gain access to user's private information. (CVE-2015-6644) * It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces special strings for obtaining attribute values with system property. This could allow an attacker to determine values of system properties at the attacked system by formatting the SAML request ID field to be the chosen system property which could be obtained in the "InResponseTo" field in the response. (CVE-2017-2582) * It was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). Security Fix(es): * It was found that Apache Lucene would accept an object from an unauthenticated user that could be manipulated through subsequent post requests. (CVE-2017-5645) * The hotrod java client in infinispan automatically deserializes bytearray message contents in certain events. The purpose of this text-only errata is to inform you about the security issues fixed in this release. Security Fix(es): * bsh2: remote code execution via deserialization (CVE-2016-2510) * log4j: Socket receiver deserialization vulnerability (CVE-2017-5645) * uima: XML external entity expansion (XXE) can allow attackers to execute arbitrary code (CVE-2017-15691) * mysql-connector-java: Connector/J unspecified vulnerability (CPU October 2018) (CVE-2018-3258) * thrift: Improper Access Control grants access to files outside the webservers docroot path (CVE-2018-11798) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Installation instructions are available from the Fuse 7.3.0 product documentation page: https://access.redhat.com/documentation/en-us/red_hat_fuse/7.3/ 4. 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). Bugs fixed (https://bugzilla.redhat.com/): 1441205 - CVE-2017-5647 tomcat: Incorrect handling of pipelined requests when send file was used 1441223 - CVE-2017-5648 tomcat: Calls to application listeners did not use the appropriate facade object 1443635 - CVE-2017-5645 log4j: Socket receiver deserialization vulnerability 1459158 - CVE-2017-5664 tomcat: Security constrained bypass in error page mechanism 5. (CVE-2017-7525) Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: rh-java-common-log4j security update Advisory ID: RHSA-2017:1417-01 Product: Red Hat Software Collections Advisory URL: https://access.redhat.com/errata/RHSA-2017:1417 Issue date: 2017-06-08 CVE Names: CVE-2017-5645 ===================================================================== 1.
