## Description

A deserialization flaw was discovered in the jackson-databind in versions
before 2.8.10 and 2.9.1, which could allow an unauthenticated user to
perform code execution by sending the maliciously crafted input to the
readValue method of the ObjectMapper. This issue extends the previous flaw
CVE-2017-7525 by blacklisting more classes that could be used maliciously.

### From the Ubuntu Security Team

It was discovered that Jackson Databind incorrectly handled
deserialization. An attacker could possibly use this issue to execute
arbitrary code.
