Impact

This CVE is introduced by the Go standard library.

Unfortunately it is not possible for us to rebuild to remediate this CVE.

Localstack fetches a pre-built binary providing a custom lambda runtime from the repository at https://github.com/localstack/lambda-runtime-init/

Upstream will need to publish a rebuilt version of the runtime

Status

Under investigation
