CVSS: 8.2EPSS: 0%CPEs: 4EXPL: 1CVE-2022-35936 – Ethermint DoS through Unintended Contract Selfdestruct
https://notcve.org/view.php?id=CVE-2022-35936
Ethermint is an Ethereum library. In Ethermint running versions before `v0.17.2`, the contract `selfdestruct` invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in the `DeleteAccount`function, all contracts that used the identical bytecode (i.e shared the same `CodeHash`) will also stop working once one contract invokes `selfdestruct`, even though the other contracts did not invoke the `selfdestruct` OPCODE. This vulnerability has been patched in Ethermint version v0.18.0. The patch has state machine-breaking changes for applications using Ethermint, so a coordinated upgrade procedure is required. • https://github.com/evmos/ethermint/blob/c9d42d667b753147977a725e98ed116c933c76cb/x/evm/keeper/statedb.go#L199-L203 https://github.com/evmos/ethermint/commit/144741832007a26dbe950512acbda4ed95b2a451 https://github.com/evmos/ethermint/security/advisories/GHSA-f92v-grc2-w2fg • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-43839 – Drainage of FeeCollector's Block Transaction Fees
https://notcve.org/view.php?id=CVE-2021-43839
Cronos is a commercial implementation of a blockchain. In Cronos nodes running versions before v0.6.5, it is possible to take transaction fees from Cosmos SDK's FeeCollector for the current block by sending a custom crafted MsgEthereumTx. This problem has been patched in Cronos v0.6.5. There are no tested workarounds. All validator node operators are recommended to upgrade to Cronos v0.6.5 at their earliest possible convenience. • https://github.com/crypto-org-chain/cronos/commit/150ef237b37ac28c8136e1c0f494932860b9ebe8 https://github.com/crypto-org-chain/cronos/pull/270 https://github.com/crypto-org-chain/cronos/security/advisories/GHSA-f854-hpxv-cw9r • CWE-670: Always-Incorrect Control Flow Implementation •
