Description

MinIO is a multi-cloud object storage solution. Starting with version RELEASE.2019-09-25T18-25-51Z and ending with version RELEASE.2022-06-02T02-11-04Z, MinIO is vulnerable to an unending go-routine buildup while keeping connections established due to HTTP clients not closing the connections. Public-facing MinIO deployments are most affected. Users should upgrade to RELEASE.2022-06-02T02-11-04Z to receive a patch. One possible workaround is to use a reverse proxy to limit the number of connections being attempted in front of MinIO, and actively rejecting connections from such malicious clients.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

2019-09-25t18-25-51z ≤ v < 2022-06-02t02-11-04z>= RELEASE.2019-9-25T18-25-51Z, < RELEASE.2022-6-2T2-11-4Z
Affected range stops below 2022-06-02t02-11-04z, so it looks safe — our inference, not a vendor statement
