vyper performs incorrect topic logging in raw_log

Summary Incorrect values can be logged when rawlog builtin is called with memory or storage arguments to be used as topics. A contract search was performed and no vulnerable contracts were found in production. In particular, no uses of rawlog were found at all in production; it is apparently not ...

GHSA-R56X-J438-VW5M vyper performs double eval of the slice start/length args in certain cases

Summary Using the slice builtin can result in a double eval vulnerability when the buffer argument is either msg.data, self.code or .code and either the start or length arguments have side-effects. A contract search was performed and no vulnerable contracts were found in production. Having...

GHSA-M2V9-W374-5HJ9 vyper default functions don't respect nonreentrancy keys

Summary Prior to v0.3.0, default functions did not respect the @nonreentrancy decorator and the lock was not emitted. This is a known bug and was already visible in the issue tracker https://github.com/vyperlang/vyper/issues/2455, but it is being re-issued as an advisory so that tools relying on...

CVE-2024-32649

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the sqrt builtin can result in double eval vulnerability when the argument has side-effects. It can be seen that the buildIR function of the sqrt builtin doesn't cache the argument to...

CVE-2024-32646

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the slice builtin can result in a double eval vulnerability when the buffer argument is either msg.data, self.code or .code and either the start or length arguments have side-effects...

CVE-2024-32648 vyper default functions don't respect nonreentrancy keys

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Prior to version 0.3.0, default functions don't respect nonreentrancy keys and the lock isn't emitted. No vulnerable production contracts were found. Additionally, using a lock on a default function is a very sparsely...

CVE-2024-32646

Vyper CVE-2024-32646 affects the Pythonic smart contract language. The vulnerability concerns the builtin slice when the buffer is msg.data, self.code, or .code and either the start or length has side-effects, causing a double evaluation of those side-effects. It is triggerable only in versions e...

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

Internal emails suggest that the company continued to provide gunshot data to police in cities where its contracts had been canceled...

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...

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...
