GSD-2021-1002463 mtd: rawnand: fsmc: Fix timing computation

mtd: rawnand: fsmc: Fix timing computation This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.4.165 by commit...

Incentivizer rewards are unclear and can be more than allotted?

Handle cmichel Vulnerability details Note that the Incentivizer.create allocates programInfo.amount.sum tokens to be rewarded. It's unclear how the rewards that are actually paid out see Program.unsettled over the duration relate to this value. The ProgramInfo.amountPerShare returns the...

_getFirstSample returns wrong sample if count < sampleMemory

Handle cmichel Vulnerability details The MovingAverage.sol contract defines several variables that in the end make the samples array act as a ring buffer: sampleMemory: The total length buffer size of the samples array. samples is initialized with sampleMemory zero observations. counter: The...

Inaccurate fees computation

Handle cmichel Vulnerability details The MixinTransfer.shareKey function wants to compute a fee such that time + fee time == timeRemaining timePlusFee: uint fee = getTransferFeekeyOwner, timeShared; uint timePlusFee = timeShared + fee; However, if the time remaining is less than the computed fee...

OverlayV1UniswapV3Market computes wrong market liquidity

Handle cmichel Vulnerability details The OverlayV1UniswapV3Market.fetchPricePoint tries to compute the market depth in OVL terms as marketLiquidity in ETH / ovlPrice in ETH per OVL. To get the market liquidity in ETH and not the other token pair, it uses the ethIs0 boolean. marketLiquidity = ethI...

Diffie-Hellman Key Agreement Protocol 资源管理错误漏洞

The Diffie-Hellman Key Agreement Protocol is a key negotiation protocol. It was originally described in Diffie and Hellman's seminal paper on public key cryptography. The key negotiation protocol allows Alice and Bob to exchange public key values and securely compute a shared key K based on...

commit burn yields wrong amountOut computation

Handle cmichel Vulnerability details The PoolCommitter.commit function first adds the amount to the shadow pool shadowPoolscommitType = shadowPoolscommitType + amount and then computes the amountOut with this updated value already: PoolSwapLibrary.getWithdrawAmountOnBurn IERC20tokens1.totalSupply...

Wrong keeper reward computation

Handle cmichel Vulnerability details The PoolKeeper.keeperReward computation mixes WADs and Quads which leads to issues. 1. Note that keeperTip returns values where 1 = 1%, and 100 = 100%, the same way BASETIP = 5 = 5%. Thus tipPercent = ABDKMathQuad.fromUIntkeeperTip is a Quad value of this keep...

Wrong reward calculation

Handle 0xsanson Vulnerability details Impact In ConcentratedLiquidityPoolManager, an user can claimReward of a subscribed position. In order to compute the correct amount, secondsUnclaimed needs to be calculated, but it's implemented incorrectly: uint256 secondsUnclaimed = maxTime -...

Cannot claim reward

Handle cmichel Vulnerability details The ConcentratedLiquidityPoolManager.claimReward requires stake.initialized but it is never set. It also performs a strange computation as 128 - incentive.secondsClaimed which will almost always underflow and revert the transaction. Impact One cannot claim...

IndexPool initial LP supply computation is wrong

Handle cmichel Vulnerability details The IndexPool.constructor function already mints INITPOOLSUPPLY = 100 1e18 = 1e20 LP tokens to the zero address. When trying to use the pool, someone has to provide the actual initial reserve tokens in mint. On the first mint, the pool reserves are zero and th...

absolute difference is not calculated properly when a > b in MathUtils

Handle hack3r-0m Vulnerability details the difference is computed incorrectly when a b. As it only used in within1 function, scope narrows down to where differencea, b It is possible to decrease the denominator and increase the value of the numerator when calculating y using constants and input t...
