ConstantProductPool.burnSingle swap amount computations should use balance

Handle cmichel Vulnerability details The ConstantProductPool.burnSingle function is basically a burn followed by a swap and must therefore act the same way as calling these two functions sequentially. The token amounts to redeem amount0, amount1 are computed on the balance not the reserve. Howeve...

HybridPool's reserve is converted to "amount" twice

Handle cmichel Vulnerability details The HybridPool's reserves are stored as Bento "amounts" not Bento shares in updateReserves because balance converts the current share balance to amount balances. However, when retrieving the reserve0/1 storage fields in getReserves, they are converted to amoun...

Unsafe cast in IndexPool mint leads to attack

Handle cmichel Vulnerability details The IndexPool.mint function performs an unsafe cast of ratio to the uint120 type: uint120 ratio = uint120divtoMint, totalSupply; Note that toMint is chosen by the caller and when choosing toMint = 2120 totalSupply / BASE, the ratio variable will be 2120 and th...

IndexPool.mint The first liquidity provider is forced to supply assets in the same amount, which may cause a significant amount of fund loss

Handle WatchPug Vulnerability details When reserve == 0, amountIn for all the tokens will be set to the same amount: ratio, regardless of the weights, decimals and market prices of the assets. The first liquidity provider may not be aware of this so that it may create an arbitrage opportunity for...

GHSA-X7VR-C387-8W57 Integer Overflow/Infinite Loop in the http crate

HeaderMap::reserve used usize::nextpoweroftwo to calculate the increased capacity. However, nextpoweroftwo silently overflows to 0 if given a sufficiently large number in release mode. If the map was not empty when the overflow happens, the library will invoke self.grow0 and start infinite probin...

GHSA-MH6H-F25P-98F8 Uncontrolled memory consumption in protobuf

GHSA-27J5-4P9V-PP67 `std::abort` raised from `TensorListReserve`

Impact Providing a negative element to numelements list argument of tf.rawops.TensorListReserve causes the runtime to abort the process due to reallocating a std::vector to have a negative number of elements: python import tensorflow as tf tf.rawops.TensorListReserve elementshape = tf.constant1,...

GHSA-H6JH-7GV5-28VG Bad alloc in `StringNGrams` caused by integer conversion

Impact The implementation of tf.rawops.StringNGrams is vulnerable to an integer overflow issue caused by converting a signed integer value to an unsigned one and then allocating memory based on this value. python import tensorflow as tf tf.rawops.StringNGrams data='','', datasplits=0,2, separator...

PYSEC-2021-557

TensorFlow is an end-to-end open source platform for machine learning. In affected versions providing a negative element to numelements list argument of tf.rawops.TensorListReserve causes the runtime to abort the process due to reallocating a std::vector to have a negative number of elements. The...

Dividend reward can be gamed

Handle cmichel Vulnerability details The Router.addDividend function tells the reserve to send dividends to the pool depending on the fees. The attacker provides LP to a curated pool. Ideally, they become a large LP holder to capture most of the profit, they should choose the smallest liquidity...

_wethWithdrawTo is vulnerable re-entrancy

Handle pauliax Vulnerability details Impact function withdrawBorrowETH invokes wethWithdrawTo and later checkMinReserve, however, the check of reserve is not necessary here, as function wethWithdrawTo also does that after transferring the ether. However, this reserve check might be bypassed as...

Awarding takes reserve fee several times

Handle cmichel Vulnerability details The PrizePool.captureAwardBalance function takes fees repeatedly on the same interest. One would expect unaccountedPrizeBalance to be 0 in any repeated calls, but it's not. Assume the following example scenario with a 10% reserve fee: user calls...

CVE-2021-3489

The eBPF RINGBUF bpfringbufreserve function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee "bp...
