Description

A flaw was found in Node.js. These vulnerabilities include remote code execution, Cross-site scripting (XSS), application crashes due to missing input validation of hostnames returned by Domain Name Servers in the Node.js DNS library, which can lead to the output of wrong hostnames (leading to Domain hijacking) and injection vulnerabilities in applications using the library.

Statement

Red Hat Quay from version 3.4 consumes nodejs from RHEL, so security tracking is provided by the container health index on the customer portal [1]. Additionally there is no impact from this issue on Quay 3.3 and 3.2 because nodejs is only used at build time and is no longer shipped, starting with Quay 3.5 [2]. [1] https://catalog.redhat.com/software/containers/quay/quay-rhel8/600e03aadd19c7786c43ae49?container-tabs=security [2] https://issues.redhat.com/browse/PROJQUAY-1409 Therefore Quay component is marked as "Will not fix" with impact LOW.
