SCA: security update for scratch-vm (GHSA-vc9j-fhvv-8vrf)

critical Tenable Self-Hosted Container Security Plugin ID 419262

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- MIT Lifelong Kindergarten Scratch scratch-vm before 0.2.0-prerelease.20200714185213 loads extension URLs
from untrusted project.json files with certain _ characters, resulting in remote code execution because
the URL's content is treated as a script and is executed as a worker. The responsible code is
getExtensionIdForOpcode in serialization/sb3.js. The use of _ is incompatible with a protection mechanism
in older versions, in which URLs were split and consequently deserialization attacks were prevented. NOTE:
the scratch.mit.edu hosted service is not affected because of the lack of worker scripts. (CVE-2020-14000)
