Description

A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.

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.
