exfiltration/XXE in some JDK classes
CVE: CVE-2018-14720
Component: jackson-databind
CWE: CWE-611
Severity: Moderate
CVSS v3: 7.5/CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Release date: 2018-07-27T00:00:00+00:00

A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the slf4j, flex messaging, sun DRSHelper and JAX-WS gadgets when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.

Statement: Red Hat Satellite 6 is not affected by this issue, since its only supported Java runtime (openJDK) doesn't bundle the com.sun.deploy.security.ruleset.DRSHelper class.

Red Hat Enterprise Virtualization 4 is not affected by this issue, since its only supported Java runtime (openJDK) doesn't bundle the com.sun.deploy.security.ruleset.DRSHelper class.

The following conditions are needed for an exploit, we recommend avoiding all if possible 
* Deserialization from sources you do not control
* `enableDefaultTyping()`
* `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
