Description

Red Hat JBoss Fuse, based on Apache ServiceMix, provides a small-footprint, flexible, open source enterprise service bus and integration platform.

Security Fix(es):

It was found that JGroups did not require necessary headers for encrypt and auth protocols from new nodes joining the cluster. An attacker could use this flaw to bypass security restrictions, and use this vulnerability to send and receive messages within the cluster, leading to information disclosure, message spoofing, or further possible attacks. (CVE-2016-2141)

A deserialization flaw allowing remote code execution was found in the BeanShell library. If BeanShell was on the classpath, it could permit code execution if another part of the application deserialized objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the BeanShell library. (CVE-2016-2510)

It was found that Apache Shiro uses a default cipher key for its "remember me" feature. An attacker could use this to devise a malicious request parameter and gain access to unauthorized content. (CVE-2016-4437)

A denial of service flaw was found in the way Spring processes inline DTD declarations. A remote attacker could submit a specially crafted XML file that would cause out-of-memory errors when parsed. (CVE-2015-3192)

It was found that Apache Camel's camel-xstream component was vulnerable to Java object deserialization. This vulnerability permits deserialization of data which could lead to information disclosure, code execution, or other possible attacks. (CVE-2015-5344)

It was found that Apache Camel's Jetty/Servlet permitted object deserialization. If using camel-jetty or camel-servlet as a consumer in Camel routes, then Camel will automatically deserialize HTTP requests that use the content-header: application/x-java-serialized-object. An attacker could use this vulnerability to gain access to unauthorized information or conduct further attacks. (CVE-2015-5348)

It was found that bouncycastle is vulnerable to an invalid curve attack. An attacker could extract private keys used in elliptic curve cryptography with a few thousand queries. (CVE-2015-7940)

The CVE-2016-2141 issue was discovered by Dennis Reed (Red Hat).
