Tendermint Core v0.34.0 introduced a new way of handling evidence of misbehavior. As part of this, we added a new Timestamp field to Evidence structs. 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.) In 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 \u201cin flight\u201d when it is being formed by the consensus reactor. It hasn\u2019t been finalized through network consensus yet. This means that different nodes in the network may observe different \u201clast commits\u201d when assigning a timestamp to DuplicateVoteEvidence. In 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. Tendermint 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 Votes 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. This release changes the API between the consensus and evidence reactors."

In 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. Tendermint 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 Votes 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. This release changes the API between the consensus and evidence reactors."

RemovePeer is therefore called before AddPeer, which leads to always growing memory (activeIDs map).

For each p2p connection, it allocates XXX bytes. Even though this memory is garbage collected once the connection is terminated (due to duplicate IP or reaching a maximum number of inbound peers), temporary memory spikes can lead to OOM (Out-Of-Memory) exceptions. Additionally, Tendermint does not reclaim activeID of a peer after it\u0027s removed in Mempool reactor. This does not happen all the time. It only happens when a connection fails (for any reason) before the Peer is created and added to all reactors. RemovePeer is therefore called before AddPeer, which leads to always growing memory (activeIDs map). The activeIDs map has a maximum size of 65535 and the node will panic if this map reaches the maximum. An attacker can create a lot of connection attempts (exploiting above denial of service), which ultimately will lead to the node panicking. These issues are patched in Tendermint 0.33.3 and 0.32.10."

Tendermint no limita el n\u00famero de peticiones de conexi\u00f3n P2P. Para cada conexi\u00f3n p2p, asigna XXX bytes. Aun cuando esta memoria es de tipo garbage collected una vez que se termina la conexi\u00f3n (debido a IP duplicada o que alcanza un n\u00famero m\u00e1ximo de peers entrantes), los picos de memoria temporales pueden conllevar a excepciones OOM (Fuera de la Memoria). Adicionalmente, Tendermint no recupera el \"activeID\" de un peer despu\u00e9s de que es eliminado en el reactor Mempool. Esto no sucede todo el tiempo. Solo se presenta cuando se produce un fallo de conexi\u00f3n (por cualquier motivo) antes de que el Peer sea creado y agregado a todos los reactores. RemovePeer, por lo tanto, es llamado antes \"AddPeer\", lo que conlleva a una memoria creciente siempre (mapa \"activeIDs\"). El mapa activeIDs presenta un tama\u00f1o m\u00e1ximo de 65535 y el nodo entrar\u00e1 en p\u00e1nico si este mapa alcanza el m\u00e1ximo. Un atacante puede crear muchos intentos de conexi\u00f3n (explotar por encima de la denegaci\u00f3n de servicio), lo que finalmente conllevar\u00e1 al p\u00e1nico del nodo.

      "value": "Tendermint Core is an open source Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language - and securely replicates it on many machines. Tendermint Core v0.34.0 introduced a new way of handling evidence of misbehavior. As part of this, we added a new Timestamp field to Evidence structs. 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.) In 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 \u201cin flight\u201d when it is being formed by the consensus reactor. It hasn\u2019t been finalized through network consensus yet. This means that different nodes in the network may observe different \u201clast commits\u201d when assigning a timestamp to DuplicateVoteEvidence. In 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. Tendermint 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 Votes 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. This release changes the API between the consensus and evidence reactors."

Tendermint Core versi\u00f3n v0.34.0 introdujo una nueva forma de manejar la evidencia de mal comportamiento. Como parte de esto, agregamos un nuevo campo Timestamp a las estructuras Evidence. Esta marca de tiempo se calcular\u00eda usando el mismo algoritmo que se utiliza cuando un bloque sea creado y propuesto. (Este algoritmo se basa en la marca de tiempo del \u00faltimo commit de este bloque espec\u00edfico). En Tendermint Core versiones v0.34.0-v0.34.2, el reactor de consenso es responsable de formar un DuplicateVoteEvidence siempre que se observen signos dobles. Sin embargo, el bloque actual todav\u00eda est\u00e1 \"in flight\" cuando lo est\u00e1 formando el reactor de consenso. A\u00fan no se ha finalizado mediante el consenso de la red. Esto significa que diferentes nodos en la red pueden observar diferentes \"last commits\" al asignar una marca de tiempo a DuplicateVoteEvidence. A su vez, diferentes nodos podr\u00edan formar objetos DuplicateVoteEvidence a la misma altura pero con diferentes marcas de tiempo. Un objeto DuplicateVoteEvidence (con una marca de tiempo) finalmente se finalizar\u00e1 en el bloque, pero esto significa que cualquier DuplicateVoteEvidence con una marca de tiempo diferente se considera inv\u00e1lido. Cualquier nodo que form\u00f3 un DuplicateVoteEvidence inv\u00e1lido continuar\u00e1 proponiendo evidencia inv\u00e1lida; sus peers pueden visualizar esto y optar por desconectarse de este nodo. Este error significa que los signos dobles son vectores de DoS en Tendermint Core versiones v0.34.0-v0.34.2. Tendermint Core versi\u00f3n v0.34.3 es una versi\u00f3n de seguridad que corrige este error. A partir de la versi\u00f3n 0.34.3, DuplicateVoteEvidence ya no est\u00e1 formado por el reactor de consenso; m\u00e1s bien, el reactor de consenso pasa los Votos mismos al EvidencePool, que ahora es responsable de formar un DuplicateVoteEvidence. EvidencePool posee informaci\u00f3n de marca de tiempo que debe ser consistente en toda la red, lo que significa que un DuplicateVoteEvidence formado en este reactor debe tener marcas de tiempo consistentes. Esta versi\u00f3n cambia la API entre los reactores de consenso y evidencia"
