RHSA-2017:3115 - Security Advisory

Topic

An update is now available for Red Hat JBoss Fuse and Red Hat JBoss A-MQ.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

Red Hat JBoss Fuse, based on Apache ServiceMix, provides a small-footprint, flexible, open source enterprise service bus and integration platform. Red Hat JBoss A-MQ, based on Apache ActiveMQ, is a standards compliant messaging system that is tailored for use in mission critical applications.

This patch is an update to Red Hat JBoss Fuse 6.3 and Red Hat JBoss A-MQ 6.3. It includes bug fixes and enhancements, which are documented in the readme.txt file included with the patch files.

Security Fix(es):

• It was found that ResourceServlet in Spring Framework does not sanitize the paths that have been provided properly. An attacker can utilize this flaw to conduct directory traversal attacks. (CVE-2016-9878)
• A vulnerability was discovered in Apache Thrift client libraries that allows remote, authenticated attackers to cause an infinite recursion via vectors involving the skip function, resulting in a denial of service (DoS) condition. (CVE-2015-3254)
• A vulnerability was discovered in JSch that allows a malicious sftp server to force a client-side relative path traversal in jsch's implementation for recursive sftp-get. An attacker could leverage this to write files outside the client's download basedir with effective permissions of the jsch sftp client process. (CVE-2016-5725)
