https://notcve.org/view.php?id=CVE-2023-46132
14 Nov 2023 — Hyperledger Fabric is an open source permissioned distributed ledger framework. Combining two molecules to one another, called "cross-linking" results in a molecule with a chemical formula that is composed of all atoms of the original two molecules. In Fabric, one can take a block of transactions and cross-link the transactions in a way that alters the way the peers parse the transactions. If a first peer receives a block B and a second peer receives a block identical to B but with the transactions being cr... • https://github.com/hyperledger/fabric/security/advisories/GHSA-v9w2-543f-h69m • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

18 Aug 2022 — Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. If a gateway client application sends a malformed request to a gateway peer it may crash the peer node. Version 2.4.6 checks for the malformed gateway request and returns an error to the gateway client. There are no known workarounds, users must upgrade to version 2.4.6.

07 Jul 2022 — 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. A fix has been added in commit 0f1835949 which checks for missing consensus messages and returns an error to the consensus client should the message be missing. Users are advised to upgrade to versions 2.2.7 or v2.4.5. There are no known workarounds for this issue. • https://github.com/hyperledger/fabric/commit/0f18359493bcbd5f9f9d1a9b05adabfe5da23b06 • CWE-20: Improper Input Validation •
