HIGH Summary
Hyperledger Fabric is a permissioned distributed ledger framework. In affected versions if a consensus client sends a malformed consensus request to an orderer it may crash the orderer node.

Users are advised to upgrade to versions 2.2.7 or v2.4.5. There are no known workarounds for this issue.
