A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x through 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM 1.x or 2.x jar in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server.

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4813-1 advisory.

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to obtain sensitive information. (CVE-2018-11307, CVE-2019-12086, CVE-2019-12814)

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute arbitrary code or other unspecified impact.

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute XML entity (XXE) attacks. (CVE-2018-14720)

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute server-side request forgery (SSRF). (CVE-2018-14721)

More Polymorphic Typing issues were discovered in jackson-databind.
When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM 1.x or 2.x or logback-core jar in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server.

For Debian 8 'Jessie', these problems have been fixed in version 2.4.2-2+deb8u7.

We recommend that you upgrade your jackson-databind packages.
