node-json-schema vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS

Summary:

JSON Schema could be made to crash or run programs if it opened specially
crafted input.

Software Description:
- node-json-schema: A vocabulary that allows you to validate, annotate, and 
manipulate JSON files

Details:

It was discovered that JSON Schema incorrectly handled certain inputs. If a
user or an automated system were tricked into opening a specially crafted
input file, a remote attacker could possibly use this issue to exploit
JavaScript runtimes and cause a denial of service or execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
   node-json-schema                0.2.3-1+deb10u1build0.20.04.1

Ubuntu 18.04 LTS:
   node-json-schema                0.2.3-1+deb10u1build0.18.04.1
