(https://nvd.nist.gov/vuln/detail/CVE-2018-14718):
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the slf4j-ext class from polymorphic deserialization.


(https://nvd.nist.gov/vuln/detail/CVE-2018-14719):
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization.


(https://nvd.nist.gov/vuln/detail/CVE-2018-14720):
FasterXML jackson-databind 2.x before 2.9.7 might allow attackers to conduct external XML entity (XXE) attacks by leveraging failure to block unspecified JDK classes from polymorphic deserialization.

(https://nvd.nist.gov/vuln/detail/CVE-2018-14721):
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to conduct server-side request forgery (SSRF) attacks by leveraging failure to block the axis2-jaxws class from polymorphic deserialization.

Upstream Fix: https://github.com/FasterXML/jackson-databind/commit/87d29af25e82a249ea15858e2d4ecbf64091db44
