HOW TO FIX?

Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.12.6.1,
2.13.2.1 or higher.


OVERVIEW

com.fasterxml.jackson.core:jackson-databind is a library which contains the
general-purpose data-binding functionality and tree-model for Jackson Data
Processor.

Affected versions of this package are vulnerable to Denial of Service (DoS) via
a large depth of nested objects.


DETAILS

Denial of Service (DoS) describes a family of attacks, all aimed at making a
system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching
security. Rather, they are focused on making websites and services unavailable
to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of
Service), an attack that attempts to clog network pipes to the system by
generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to
trigger such a crash or crippling of the service by using a flaw either in the
application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

 * High CPU/Memory Consumption- An attacker sending crafted requests that could
   cause the system to take a disproportionate amount of time to process. For
   example, commons-fileupload:commons-fileupload.

 * Crash - An attacker sending crafted requests that could cause the system to
   crash. For Example, npm ws package
