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)
