NVD Description

Note: Versions mentioned in the description apply only to the upstream helm-4 package and not the helm-4 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

For HTTP/1 servers, when MaxBytesReader's limit is exceeded, "Connection: close" header is automatically set without synchronization, which might race with another header being set explicitly in the server handler. As a result, an HTTP/1 server that utilizes MaxBytesReader or MaxBytesHandler can crash due to runtime panic if its handler reads the request body concurrently with writing the response header.
