These attacks target libp2p’s connection, stream, peer, and memory management. An attacker can cause the allocation of large amounts of memory, ultimately leading to the process getting killed by the host’s operating system. While a connection manager tasked with keeping the number of connections within manageable limits has been part of go-libp2p, this component was designed to handle the regular churn of peers, not a targeted resource exhaustion attack.\n\nIn the original version of the attack, the malicious node would continue opening new streams on a stream multiplexer that doesn’t provide sufficient back pressure (yamux or mplex). It is easy to defend against this one attack, but there are countless variations of this attack:\n* Opening streams and causing a non-trivial memory allocation (e.g., for multistream or protobuf parsing)\n* Creating a lot of sybil nodes and opening new connections across nodes\n\n### Patches (What to do as a go-libp2p consumer:)\n1. Update your go-libp2p dependency to go-libp2p v0.18.0 or greater (current version as of publish date is [v0.24.0](https://github.com/libp2p/go-libp2p/releases/tag/v0.24.0).)\n - Note: **It's recommend that you update to `v0.21.0` onwards** as you’ll get some useful functionality that will help in production environments like better metrics around resource usage, Grafana dashboards around resource usage, allow list support, and default autoscaling limits. [Please see the v0.21.0 release notes for more info.](https://github.com/libp2p/go-libp2p/releases/tag/v0.21.0))\n\n2. Determine appropriate limits for your application - go-libp2p sets up a resource manager with the default limits if none are provided. For default definitions please see [limits_defaults.go](https://github.com/libp2p/go-libp2p/blob/master/p2p/host/resource-manager/limit_defaults.go). These limits are also set to automatically scale, this is done using the [AutoScale method of the ScalingLimitConfig](https://github.com/libp2p/go-libp2p/blob/master/p2p/host/resource-manager/README.md#scaling-limits). We recommend you [tune your limits as described here](https://github.com/libp2p/go-libp2p/blob/master/p2p/host/resource-manager/README.md#how-to-tune-your-limits).\n\n3. Configure your node to be attack resilient. See [how to respond to an attack and identify misbehaving peers here](https://docs.libp2p.io/concepts/security/dos-mitigation/#responding-to-an-attack). Then setup automatic blocking with fail2ban using canonical libp2p log lines: [guide on how to do so here](https://docs.libp2p.io/concepts/security/dos-mitigation/#how-to-automate-blocking-with-fail2ban).\n\n#### Examples\n* Lotus’ integration can be found in https://github.com/filecoin-project/lotus/blob/master/node/modules/lp2p/rcmgr.go. Lotus reads user-configured resource limits from a limits.json file into the root directory. This allows users to share their resource manager configuration independent of any other configurations.\n* Kubo’s (formerly go-ipfs) integration can be found in https://github.com/ipfs/go-ipfs/blob/master/core/node/libp2p/rcmgr.go. Kubo reads the limits from the IPFS config file.\n\n**Note:** go-libp2p still implements the [connection manager](https://github.com/libp2p/go-libp2p/tree/master/p2p/net/connmgr) mentioned above. The connection manager is a component independent of the resource manager, which aims to keep the number of libp2p connections between a low and a high watermark. When modifying connection limits, it’s advantageous to keep the configuration of these components consistent, i.e., when setting a limit of N concurrent connections in the resource manager, the high watermark should be at most (and ideally slightly less) than N.\n\n### Workarounds\nAlthough there are no workarounds within go-libp2p, some range of attacks can be mitigated using OS tools (like manually blocking malicious peers using `iptables` or `ufw` ) or making use of a load balancer in front of libp2p nodes.\n\nHowever these require direct action \u0026 responsibility on your part and are no substitutes for upgrading go-libp2p. Therefore, we highly recommend upgrading your go-libp2p version for the way it enables tighter scoped limits and provides visibility into and easier reasoning about go-libp2p resource utilization.\n\n### References\nPlease see our DoS Mitigation page for more information on how to incorporate mitigation strategies, monitor your application, and respond to attacks: https://docs.libp2p.io/reference/dos-mitigation/. \n\nPlease see the related disclosure for rust-libp2p: https://github.com/libp2p/rust-libp2p/security/advisories/GHSA-jvgw-gccv-q5p8 and js-libp2p: https://github.com/libp2p/js-libp2p/security/advisories/GHSA-f44q-634c-jvwv\n\n#### For more information\n\nIf you have any questions or comments about this advisory email us at [security@libp2p.io](mailto:security@libp2p.io)"},"Suggestion":{"Summary":"Resource exhaustion in github.com/libp2p/go-libp2p","Description":"go-libp2p is vulnerable to targeted resource exhaustion attacks.

Formally speaking, infinity, or the identity element of the elliptic curve group, is a member of the group, and the group-check should allow it. An initial review of blst users on GitHub did not uncover any use of this function with the complementary infinity check. This optional check was added as a convenience feature because despite infinity being a legitimate member of the group, individual signatures should never be infinite (as it is equivalent to having zero for the secret key), and observing one should raise a flag.\n\n### Description\n\nThe vulnerable function is declared as `SigValidate(sigInfcheck bool) bool` and if called with `sigInfcheck` argument set to `true`, the group-check was omitted. The group-check is required to be performed on untrusted input, because the pairing, the corner-stone operation of the signature scheme, is defined only on points that are members of a specific cyclic group, which is a subset of all the possible points on elliptic curves in question. Submitting an untrusted point outside the group opens up the possibility of accepting an alternative signature for a chosen message.\n\nIt should be noted that the SigValidate call is not the only way to perform the group-checks. There are optional checks integrated into various other verification methods, such as `Verify`, `AggregateVerify`, etc., as well as signature aggregation methods, such as `PairingAggregate*`. The reason why there are multiple options is that the group-check is a relatively expensive operation, and application developers are arguably entitled the freedom to choose when it's performed.\n\n### Patches\n\nThis issue has been resolved in the v0.3.11 release and users are advised to update if their application is affected or alternatively omit the complementary infinity check.\n\n### Credits\n\nA special thanks to Yunjong Jeong (@blukat29) for the discovery and disclosure of this vulnerability.\n"},"Suggestion":{"Summary":"Blst fails to perform group signature validation","Description":"When complemented with a check for infinity, blst skips performing a signature group-check.

This could lead to an overflow and an allocation of memory with excessive size value.\n\nExample:\n\n```go\npackage main\n\nimport (\n\t\"github.com/gagliardetto/binary\" // any version before v0.7.1 is vulnerable\n\t\"log\"\n)\n\ntype MyStruct struct {\n\tField1 []byte // field is a slice (could be a slice of any type)\n}\n\nfunc main() {\n\t// Let's assume that the data is coming from the blockchain:\n\tdata := []byte{0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10}\n\t\n\tvar val MyStruct\n\t// - To determine the size of the val.Field1 slice, the decoder will read the length\n\t// of the slice from the data itself without any checks on the size of it.\n\t//\n\t// - This could lead to an allocation of memory with excessive size value.\n\t// Which means: []byte{0x01, 0x02, 0x03, 0x04} will be read as the length\n\t// of the slice (= 67305985) and then an allocation of memory with 67305985 bytes will be made.\n\t//\n\tdec := binary.NewBorshDecoder(data)\n\terr := dec.Decode(\u0026val) // or binary.UnmarshalBorsh(\u0026val, data) or binary.UnmarshalBin(\u0026val, data) etc.\n\tif err != nil {\n\t\tlog.Fatal(err)\n\t}\n}\n```\n\n### Patches\n\u003e _Has the problem been patched?

While the function was commented as deprecated, the format of the comment was however not following the [convention](https://zchee.github.io/golang-wiki/Deprecated/) for deprecated functions, and might not have been picked up by tooling like editors. This has now been fixed. Users are still encouraged to use the capabilities feature over the deprecated `WithUnsafeBuiltins` function.\n\n**If you cannot upgrade**, consider using capabilities instead:\n\nCode like this using the `github.com/open-policy-agent/opa/ast` package:\n```go\n// VULNERABLE with OPA \u003c= 0.43.0\nunsafeBuiltins := map[string]struct{}{\n\tast.HTTPSend.Name: struct{}{},\n}\ncompiler := ast.NewCompiler().WithUnsafeBuiltins(unsafeBuiltins)\n```\n\nneeds to be changed to this:\n```go\ncaps := ast.CapabilitiesForThisVersion()\nvar j int\nfor i, bi := range caps.Builtins {\n\tif bi.Name == ast.HTTPSend.Name {\n\t\tj = i\n\t\tbreak\n\t}\n}\ncaps.Builtins[j] = caps.Builtins[len(caps.Builtins)-1] // put last element into position j\ncaps.Builtins = caps.Builtins[:len(caps.Builtins)-1] // truncate slice\n\ncompiler := ast.NewCompiler().WithCapabilities(caps)\n```\n\nWhen using the `github.com/open-policy-agent/opa/rego` package:\n\n```go\n// VULNERABLE with OPA \u003c= 0.43.0\nr := rego.New(\n\t// other options omitted\n\trego.UnsafeBuiltins(map[string]struct{}{ast.HTTPSend.Name: struct{}{}}),\n)\n```\n\nneeds to be changed to\n```go\nr := rego.New(\n\t// other options omitted\n\trego.Capabilities(caps),\n)\n```\nwith `caps` defined above.\n\nNote that in the process, some error messages will change: `http.send` in this example will no longer be \"unsafe\" and thus forbidden, but it will simply become an \"unknown function\".\n\n### References\n\n* Fix commit on `main`: https://github.com/open-policy-agent/opa/commit/25a597bc3f4985162e7f65f9c36599f4f8f55823\n* Fix commit in 0.43.1 release: https://github.com/open-policy-agent/opa/commit/3e8c754ed007b22393cf65e48751ad9f6457fee8, release page for 0.43.1: https://github.com/open-policy-agent/opa/releases/tag/v0.43.1\n* Function mocking feature introduced in https://github.com/open-policy-agent/opa/pull/4540 and https://github.com/open-policy-agent/opa/pull/4616 \n* Documentation on the [capabilities](https://www.openpolicyagent.org/docs/latest/deployments/#capabilities) feature, which is the preferred way of providing a list of allowed built-in functions.

As part of this, [we added a new `Timestamp` field to `Evidence` structs](https://github.com/tendermint/tendermint/pull/5219). This timestamp would be calculated using the same algorithm that is used when a block is created and proposed. (This algorithm relies on the timestamp of the last commit from this specific block.) \n\nIn Tendermint Core v0.34.0-v0.34.2, the `consensus` reactor is responsible for forming `DuplicateVoteEvidence` whenever double signs are observed. However, the current block is still “in flight” when it is being formed by the `consensus` reactor. It hasn’t been finalized through network consensus yet. This means that different nodes in the network may observe different “last commits” when assigning a timestamp to `DuplicateVoteEvidence.`\n\nIn turn, different nodes could form `DuplicateVoteEvidence` objects at the same height but with different timestamps. One `DuplicateVoteEvidence` object (with one timestamp) will then eventually get finalized in the block, but this means that any `DuplicateVoteEvidence` with a different timestamp is considered invalid. Any node that formed invalid `DuplicateVoteEvidence` will continue to propose invalid evidence; its peers may see this, and choose to disconnect from this node. This bug means that double signs are DoS vectors in Tendermint Core v0.34.0-v0.34.2. \n\nTendermint Core v0.34.3 is a security release which fixes this bug. As of v0.34.3, `DuplicateVoteEvidence` is no longer formed by the `consensus` reactor; rather, the `consensus` reactor passes the `Vote`s themselves into the `EvidencePool`, which is now responsible for forming `DuplicateVoteEvidence`. The `EvidencePool` has timestamp info that should be consistent across the network, which means that `DuplicateVoteEvidence` formed in this reactor should have consistent timestamps. \n\nThis release changes the API between the `consensus` and `evidence` reactors. \n\n### Impact\n\nThis is a denial-of-service vector which impacts networks running Tendermint Core v0.34.0 - v0.34.2.\n\n### Remediation\n\nThis problem has been patched in Tendermint Core v0.34.3.

This property can be exploited by the database to expose two different transaction entries depending on the other transaction that the user requested consistency proof for.\n\nIn practice this could lead to a following scenario:\n\n* a client requests a verified write operation\n* the server responds with a proof for the transaction\n* client stores the state value retrieved from the server and expects it to be a confirmation of that write and all the history of the database before that transaction\n* a series of validated read / write operations is performed by the client, each accompanied by a successfully validated consistency proof and update of the client state\n* the client requests verified get operation on the transaction it has written before (and that was verified with a proof from the server)\n* the server replies with a completely different transaction that can be properly validated according to the currently stored db state on the client side\n\n### Patches\n\nThe following Go SDK versions is not vulnerable:\n\n| **SDK** | **Version** |\n|-------|------------|\n| [go](pkg.go.dev/github.com/codenotary/immudb/pkg/client) | 1.4.1 |\n\n### Workarounds\n\nInvalid proofs can not be generated in a normal immudb server and will be detected by a genuine replica server.\nTo ensure that the server does not produce invalid proofs and to check that the history presented by the server\ndoes not contain falsified transactions, one should run a genuine immudb replica server in a safe environment\nand fully synchronize all databases with the primary.\n\n### References\n\n* https://github.com/codenotary/immudb/tree/master/docs/security/vulnerabilities/linear-fake\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open a discussion in [immudb Discussions](https://github.com/codenotary/immudb/discussions/new)\n* Email us at [immudb-security@codenotary.com](mailto:immudb-security@codenotary.com)\n"},"Suggestion":{"Summary":"Insufficient verification of proofs in github.com/codenotary/immudb","Description":"In certain scenarios, a malicious immudb server can provide a falsified proof that will be accepted by the client SDK signing a falsified transaction replacing the genuine one.
