CVE-2017-5645

TITLE

Red Hat Security Advisory 2017-3400-01

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. 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. Solution: The References section of this erratum contains a download link (you must log in to download the update). Description: Red Hat JBoss BPM Suite is a business rules and processes management system for the management, storage, creation, modification, and deployment of JBoss rules and BPMN2-compliant business processes. (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. (CVE-2017-5645) * 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-2017-7525) Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525. Description: The eap7-jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2). Refer to the JBoss Enterprise Application Platform 7.0.8 Release Notes, linked to in the References section, for information on the most significant bug fixes and enhancements included in this release. (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(). Solution: Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications. Bugs fixed (https://bugzilla.redhat.com/): 1410481 - CVE-2017-2582 picketlink, keycloak: SAML request parser replaces special strings with system properties 1443635 - CVE-2017-5645 log4j: Socket receiver deserialization vulnerability 1444015 - CVE-2015-6644 bouncycastle: Information disclosure in GCMBlockCipher 1455566 - CVE-2014-9970 jasypt: Vulnerable to timing attack against the password hash comparison 1465573 - CVE-2017-7536 hibernate-validator: Privilege escalation when running under the security manager 6.
