soroban-fixed-point-math security vulnerability

Soroban-Fixed-Point-Math is a mathematical computing code library open source by Script3. Versions 1.3.0 and 1.4.0 of Soroban-Fixed-Point-Math have security vulnerabilities. These vulnerabilities stem from improper handling of negative intermediate products and negative divisors in the mulDiv...

CVE-2022-29219

Lodestar is a TypeScript implementation of the Ethereum Consensus specification. Prior to version 0.36.0, there is a possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Because the developers represent uint64 values as native javascript...

PYSEC-2023-307

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine EVM. Contracts containing large arrays might underallocate the number of slots they need by 1. Prior to v0.3.8, the calculation to determine how many slots a storage variable needed used math.ceiltype.sizeinbytes / 32. T...

An attacker can manipulate the preDepositvePrice to steal from other users.

Lines of code Vulnerability details Impact The first user that stakes can manipulate the total supply of sfTokens and by doing so create a rounding error for each subsequent user. In the worst case, an attacker can steal all the funds of the next user. Proof of Concept When the first user enters...

Pricing inconsistencies introduced via rounding/truncation errors

Lines of code Vulnerability details Impact Calculating share/token prices via bonding curves which involve mathematical operations like logs and divisions can introduce small rounding errors each time. Over many transactions, these errors could accumulate and lead to pricing inconsistencies that...

Incorrect fee splitting logic

Lines of code Vulnerability details Impact The fee splitting logic does not properly attribute holder and creator rewards. By splitting fees from the total rather than incrementally, it distorts the proportional rewards earned over time. This could undermine the incentive structures and alignment...

Price inflation by locking CVX on behalf of VotiumStrategy

Lines of code Vulnerability details Impact The price of vAfEth can be inflated with severe rounding errors as a result. Proof of Concept In VotiumStrategy the price of vAfEth is calculated by function cvxInSystem public view returns uint256 uint256 total = ILockedCvxVLCVXADDRESS.lockedBalanceOf...

Price inflation pump

Lines of code Vulnerability details Impact AfEth price can be inflated until severe rounding errors occur. Proof of concept Deposit in AfEth such that totalValue == 1 and thus 1 afEth is minted. Then AfEth.price will be in the open interval $1,2$ AfEth.price $= 1$ is extremely unlikely. Deposit i...

Calculations like valueX8 and liquidity do not account for potential rounding errors

Lines of code Vulnerability details Impact These small inaccuracies could accumulate and cause the total supply of liquidity tokens to not exactly match the vault holdings. This could allow an attacker to potentially deposit tokens, get liquidity that is slightly higher than what they should base...

This could allow an attacker to potentially deposit tokens, get liquidity that is slightly higher than what they should base...

M-10 Unmitigated

Lines of code Vulnerability details Mitigation of M-10: Issue NOT mitigated Mitigated issue M-10: First 1 wei deposit can produce lose of user xETH funds in wxETH Fix: code-423n4/2023-05-xeth@fbb2972 The issue is similar to the standard inflation attack, except that instead of the attacker's...

An attacker can manipulate the preDepositvePrice to steal from other users.

In the worst case, an attacker can steal all the funds of the next user. Proof of Concept When the first user enters...

Audit Findings for BYTES Token Contract - Burn Function Vulnerabilities

Lines of code Vulnerability details Impact BYTES2.burn: The function burn allows authorized callers to burn BYTES tokens from a specific address and mint DAO taxes. However, the function does not check if the from address actually has enough BYTES tokens to burn. This means that an attacker could...

First depositor can inflate share price

Lines of code Vulnerability details Impact A well-known vulnerability for ERC4626 vaults is the inflation of the share price on the first deposit. Because AutoPxGlp and AutoPxGmx use the balance of the underlying asset for totalAssets and do not have an initial minimum deposit amount, they are al...

Minimum balance requirement for payout

Lines of code Vulnerability details Impact Payouts from PA1D.sol cannot be made unless the balance is sufficiently high, meaning Proof of Concept In PA1D.sol the payout functions payoutEth, payoutToken and payoutTokens require that balance 10000. If this is not met the recipients cannot receive...

Overflow in _baseVestedAmount() prevents claims to be retrieved

Lines of code Vulnerability details Impact Rewards of high value will be unable to be withdrawn since claimableAmount will revert. Proof of Concept In line 176, if we assume there's a claim of a token with 18 decimals and a vesting of 1 year, which is a realistic vesting period that can be observ...

Rounding errors can lead to wrong voting power

Lines of code Vulnerability details Impact The calculation of voting power in Crowdfund.getFinalContribution can lead to loss of voting power due to rounding errors. Tools Used Manual audit --- The text was updated successfully, but these errors were encountered: All reactions...

in function redeem() of TribeRedeemer users would receive less funds because of rounding error in division in previewRedeem()

Lines of code Vulnerability details Impact Function previewRedeem in TribeRedeemer has been used to calculate the amounts of tokens the user would receive for what the user transfer as redeemedToken. the user would receive a ratio of token balance of the contract which ratio is equal to amountIn ...

AttesterSlashing number overflow

Impact Possible consensus split given maliciously-crafted AttesterSlashing or ProposerSlashing being included on-chain. Since we represent uint64 values as native javascript numbers, there is an issue when those variables with large greater than 2^53 uint64 values are included on chain. In those...
