3. Description:

The jackson-databind package provides general data-binding functionality
for Jackson, which works on top of Jackson core streaming API.

Security Fix(es):

* A deserialization flaw was discovered in the jackson-databind which could
allow an unauthenticated user to perform code execution by sending
maliciously crafted input to the readValue method of ObjectMapper. This
issue extends upon the previous flaws CVE-2017-7525 and CVE-2017-15095 by
blacklisting more classes that could be used maliciously. (CVE-2017-17485)
