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 the
maliciously crafted input to the readValue method of the ObjectMapper.
(CVE-2017-7525)

* 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. (CVE-2017-15095, CVE-2017-17485)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting
CVE-2017-7525 and CVE-2017-15095 and 0c0c0f from ??? for reporting
CVE-2017-17485.
