Red Hat Security Advisory 2018-0342-01 - The jackson-databind package provides general data-binding functionality for Jackson, which works on top of Jackson core streaming API. Security Fix: 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. Further classes that an attacker could use to achieve code execution through deserialisation were discovered, and added to the blacklist introduced by CVE-2017-7525.
