Security Advisory: Important
An update is now available for Red Hat JBoss Data Virtualization.
Red Hat Product Security has rated this update as having a security impact of Important. 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.
Red Hat JBoss Data Virtualization is a lean data integration solution that provides easy, real-time, and unified data access across disparate sources to multiple applications and users. JBoss Data Virtualization makes data spread across physically distinct systems - such as multiple databases, XML files, and even Hadoop systems - appear as a set of tables in a local database.
This release of Red Hat JBoss Data Virtualization 6.3 Update 7 serves as a replacement for Red Hat JBoss Data Virtualization 6.3 Update 6, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
- A deserialization flaw was discovered in the jackson-databind which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. (CVE-2017-7525)
- 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 denial of service vulnerability was discovered in ZooKeeper which allows an attacker to dramatically increase CPU utilization by abusing "wchp/wchc" commands, leading to the server being unable to serve legitimate requests. (CVE-2017-5637)
Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525.
