## Overview

FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.

## Affected

- `jackson-databind >= 2.0.0, < 2.6.7.3`
- `jackson-databind >= 2.7.0, < 2.7.9.6`
- `jackson-databind >= 2.8.0, < 2.8.11.4`
- `jackson-databind >= 2.9.0, < 2.9.9.1`
- `debian_linux = 8.0`
- `enterprise_linux = 7.0`
- `enterprise_linux = 7.4`
- `enterprise_linux = 7.5`
- `enterprise_linux = 7.6`
- `enterprise_linux = 7.7`

## Remediation

Upgrade past the affected range:

- `jackson-databind 2.9.9.1`
