GHSA-8724-5XMM-W5XQ CosmWasm affected by arithmetic overflows

Some mathematical operations in cosmwasm-std use wrapping math instead of panicking on overflow for very big numbers. This can lead to wrong calculations in contracts that use these operations. Affected functions: - Uint256,512::pow / Int256,512::pow - Int256,512::neg Affected if overflow-checks ...

ShotSpotter Keeps Listening for Gunfire After Contracts Expire

Improper Synchronisation

https://github.com/evmos/evmos/ is vulnerable to Improper Synchronisation. The vulnerability is due to a lack of synchronization between two states during transaction execution, allowing for arbitrary token minting. This exploit occurs because the stateDB.Commit method updates the Cosmos SDK...

Improper Access Control

github.com/evmos/evmos is vulnerable to Improper Access Control. The vulnerability is due to Evmos allowing the creation of a vesting account at a designated address for smart contracts on the EVM, enabling attackers to front-run the creation of a contract and block legitimate contract deployment...

Evmos vulnerable to unauthorized account creation with vesting module

Impact What kind of vulnerability is it? Who is impacted? Using the vesting module, a malicious attacker can create a new vesting account at a given address, before a contract is created on that address. Addresses of smart contracts deployed to the EVM are deterministic. Therefore, it would be...

CVE-2024-27094

OpenZeppelin Contracts is a library for secure smart contract development. The Base64.encode function encodes a bytes input by iterating over it in chunks of 3 bytes. When this input is not a multiple of 3, the last iteration may read parts of the memory that are beyond the input buffer. The...

OpenZeppelin 安全漏洞

OpenZeppelin is a software application. A standard for secure blockchain applications. A security vulnerability exists in OpenZeppelin Contracts versions prior to 5.0.2 and prior to 4.9.6, which stems from the fact that the last iteration of the Base64.encode function can read portions of memory...

GHSA-75JP-VQ8X-H4CQ Wasmi Out-of-bounds Write for host to Wasm calls with more than 128 Parameters

Summary In the WASMI Interpreter, an Out-of-bounds Buffer Write will arise arise if the host calls or resumes a Wasm function with more parameters than the default limit 128, as it will surpass the stack value. This doesn’t affect calls from Wasm to Wasm, only from host to Wasm. Impact After...
