          "value": "Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. The extrinsic note_min_gas_price_target is an inherent extrinsic, meaning only the block producer can call it. To ensure correctness, the ProvideInherent trait should be implemented for each inherent, which includes the check_inherent call. This allows other nodes to verify if the input (in this case, the target value) is correct. However, prior to commit a754b3d, the check_inherent function has not been implemented for note_min_gas_price_target. This lets the block producer set the target value without verification. The target is then used to set the MinGasPrice, which has an upper and lower bound defined in the on_initialize hook. The block producer can set the target to the upper bound. Which also increases the upper and lower bounds for the next block. Over time, this could result in continuously raising the gas price, making contract execution too expensive and ineffective for users. An attacker could use this flaw to manipulate the gas price, potentially leading to significantly inflated transaction fees. Such manipulation could render contract execution prohibitively expensive for users, effectively resulting in a denial-of-service condition for the network. This is fixed in version a754b3d."

In versions 1.3.0 and 1.4.0, the `mulDiv(x, y, z)` function incorrectly handled cases where both the intermediate product $x * y$ and the divisor $z$ were negative. The logic assumed that if the intermediate product was negative, the final result must also be negative, neglecting the sign of $z$. This resulted in rounding being applied in the wrong direction for cases where both $x * y$ and $z$ were negative. The functions most at risk are `fixed_div_floor` and `fixed_div_ceil`, as they often use non-constant numbers as the divisor $z$ in `mulDiv`.  This error is present in all signed `FixedPoint` and `SorobanFixedPoint` implementations, including `i64`, `i128`, and `I256`. Versions 1.3.1 and 1.4.1 contain a patch. No known workarounds for this issue are available."

Prior to version 1.6.0, the `validateSignature` function in `validate.go` goes through the references in the `SignedInfo` block to find one that matches the signed element\u0027s ID. In Go versions before 1.22, or when `go.mod` uses an older version, there is a loop variable capture issue. The code takes the address of the loop variable `_ref` instead of its value. As a result, if more than one reference matches the ID or if the loop logic is incorrect, the `ref` pointer will always end up pointing to the last element in the `SignedInfo.References` slice after the loop. goxmlsig version 1.6.0 contains a patch."
