user fund loss in redeem() of RariMerkleRedeemer, because of division rounding error in previewRedeem() which is used in _redeem() and _multiRedeem()

Lines of code Vulnerability details Impact Because of the division rounding error in calculating baseToken amount, when users tries to redeem, they receive less baseToken for the amount of cToken they transferred to the RariMerkleRedeemer contract. This bug is more critical when cToken is a very...

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 ...

Rounding error for low decimal token

Lines of code Vulnerability details Impact Some token has low decimal USDC has only 6, as a result, the rounding may introduce substantial error in stable pair calculation, causing wrong getAmountOut quote, at the end lead to fund loss in swap function. Malicious user can abuse the wrong quote to...

Multiplication performed after division can truncate the results

Lines of code Vulnerability details Multiplication performed after division can truncate the results Impact Solidity could truncate the results, performing multiplication before division will prevent rounding/truncation in solidity math. Details This can affect variables such as slopes, interests...

The vulnerability of the Apache Xalan Java XSLT library, related to a rounding error, allows attackers to execute arbitrary code.

The vulnerability of the Apache Xalan Java XSLT library is related to an error in converting integer values when processing XSLT style sheets. Exploiting this vulnerability allows a remote attacker to execute arbitrary code...

User fund lose in addLiquidity() of LiquidityReserve by increasing (totalLockedValue / totalSupply()) to very large number by attacker

Lines of code Vulnerability details Impact Function addLiquidity suppose to do add Liquidity for the staking Token and receive lrToken in exchange. to calculate amount of IrToken codes uses this calculation: amountToMint = amount lrFoxSupply / totalLockedValue but it's possible for attacker to...

It's possible to perform DOS and fund lose in Stacking by transferring tokens directly to contract

Lines of code Vulnerability details Impact Function rebase in contract Staking calls Yieldy.rebaseprofit, and Yieldy.rebaseprofit, would revert if rebasingCredits / updatedTotalSupply was equal to 0. it's possible to transfer some STAKINGTOKEN directly to Stacking contract before or after...

fund lose because of the direct funds transfer to vault address and cause big balance() to totalSupply() ratio and cause big division error in _mintSharesFor() (this is in previous contest scope)

Lines of code Vulnerability details Impact Attacker can cause balance / totalSupply ratio to go as high as he want and then because of rounding error in mintSharesFor lower amount of share would be mint for users. if totalSupply is 0 attacker can directly transfer tokens to contract address and...

Rounding Issues In Certain Functions

Lines of code Vulnerability details Background Per EIP 4626's Security Considerations Finally, ERC-4626 Vault implementers should be aware of the need for specific, opposing rounding directions across the different mutable and view methods, as it is considered most secure to favor the Vault itsel...

GHSA-CVJ7-5F3C-9VG9 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...
