Upstream patch:
https://github.com/mongodb/mongo/commit/ee97c0699fd55b498310996ee002328e533681a3

Comment 3 Riccardo Schirone 2020-11-30 17:12:39 UTC
The flaw is in the ExprMatchExpression class. The version of mongodb as shipped in RHUI-3 does not contain that class, thus it is not affected by this flaw.

Comment 4 Yadnyawalk Tale 2020-11-30 17:35:59 UTC
Red Hat Satellite 6.6 onward does not ship the MongoDB package; however, the product consumes MongoDB from Red Hat Software Collections (RHSCL) for Red Hat Enterprise Linux. Satellite has no plans to update to a version of MongoDB released with a Server Side Public License (SSPL) which includes all versions released after October 16, 2018.
