Red Hat libvirt 安全漏洞

Red Hat libvirt is a Linux API for implementing Linux virtualization features from Red Hat, Inc. that supports a variety of Hypervisors, including Xen and KVM, as well as QEMU and a number of virtual products for other operating systems. A security vulnerability exists in Red Hat libvirt that ste...

Permit does not revert for tokens that do not implement it.

Lines of code Vulnerability details Impact Callers should not rely on permit to revert for arbitrary tokens especially if permit is used as a security check. Tokens which do not revert on permit either do not implement it or have a non-reverting fallback function. Most notable among them is WETH...

Funds added to reserves through sync are accidentally transferred out to users

Lines of code Vulnerability details Impact Wells have the ability to shift funds to other Wells as part of gas-efficient multi-pool swaps. This natspec explanation of this can be find here. The sync function is intended to synchronize the underlying token amounts with the token reserves of the...

Possible to stop trading

Lines of code Vulnerability details Impact It's possible to stop market due to division by 0 exception. So better to prevent this, because better to revert with missing minAmountOut than revert with some error, which might be complicated to detect. Proof of Concept There is a change to withdraw a...

The existence of Pump may hinder large swaps or swaps from a low liquidity pool

Lines of code Vulnerability details Impact Large swaps or swaps with low liquidity value may not work properly. Proof of Concept According to the whitepaper, the purpose of the pump is to be a multi-block MEV manipulation resistant to large changes in liquidity value. Since the Well can be create...

Subsequent liquidity providers will suffer from the loss of funds

Lines of code Vulnerability details Impact When adding liquidity, lpAmountOut is calculated using the formula: calcLpTokenSupplywellFunction, reserves - totalSupply. function calcLpTokenSupply Call memory wellFunction, uint256 memory reserves internal view returns uint256 lpTokenSupply...

There is a large precision error in sqrt calculation of lp

Lines of code Vulnerability details Impact Compared with div, there is a larger precision error in calculating lp through sqrt, so there should be a way to check whether there are excess tokens left when adding liquidity. Proof of Concept function testCalcLpTokenSupplyDiff public uint256 memory...

Well.sol::addLiquidity() Unauthorized Liquidity Addition for Fee-on-Transfer Tokens

Lines of code Vulnerability details Description The addLiquidity in the Well.sol contract allows any address to add liquidity to tokens with a fee-on-transfer mechanism. Although there is a another function available to add liquidity for Fee-on-transfer token name addLiquidityFeeOnTransfer. Howev...

GHSA-G96C-X7RH-99R3 Graylog vulnerable to insecure source port usage for DNS queries

Summary Graylog utilises only one single source port for DNS queries. Details Graylog seems to bind a single socket for outgoing DNS queries. That socket is bound to a random port number which is not changed again. This goes against recommended practice since 2008, when Dan Kaminsky discovered ho...

Calculation during rebalancing can overflow

Lines of code Vulnerability details Proof of Concept Rebalancing logic in TalosBaseStrategy will start by the strategy manager calling TalosBaseStrategy.rebalance to swap imbalanced tokens. This function will call TalosStrategySimple.doRebalance Next, PoolActions.swapEqualAmounts will be called...

The LybraRETHVault.depositEtherToMint doesn't keep record of user's ether deposits which results in loss for the user.

Lines of code Vulnerability details Impact High: User will lose his deposited ether. Proof of Concept The collateralAsset address variable which is used in LybraPeUSDVaultBase is assumed to be stETH token address Now the depositEtherToMint function from contract LybraRETHVault.sol which inherits...

Medium: wayland

Issue Overview: An internal reference count is held on the buffer pool, incremented every time a new buffer is created from the pool. The reference count is maintained as an int; on LP64 systems this can cause the reference count to overflow if the client creates a large number of wlshm buffer...

Arbitrary parameters

Lines of code Vulnerability details Impact There is no way to check that the sequence parameter is indeed a correct one Proof of Concept It is being passed straight to a function which modifies the KVStore's pools, thus it could be any value due to not being checked e. g. it could be 0,...

Lack of deadline parameter when executing swaps

Lines of code Vulnerability details Impact Deadline is not checked. The transaction may stay unexecuted for a long time, resulting in unfavourable trade when the transaction is finally executed. Proof of Concept The function OnRecvPacket is used to help users outside of Canto onboard seamlessly...

Canto pool could be drained.

Lines of code Vulnerability details Impact It was written that there a limit for 10 USDC /10 USDT /0.01 ETH, which currently equals to 10 USDT/ 10 USDC/ 18 USDT almost. These limits are for 4 Canto. Which means code accepts the Canto price at max: 2,5 USDC or equavalent. It is also written in the...

Slippage protection minOut autoSwapThreshold is not effective when swapping the token

Lines of code Vulnerability details Impact In the current model, the minimum output minOut amount for the auto-swap is set to match the autoSwapThreshold, which is fixed at 4 CANTO. This configuration might result in potential market risks due to fluctuations in the value of CANTO, potentially...
