| CVE-2023-31146 | 1 Vyperlang | 1 Vyper | 2023-08-02 | N/A | 9.1 CRITICAL |
| Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, during codegen, the length word of a dynarray is written before the data, which can result in out-of-bounds array access in the case where the dynarray is on both the lhs and rhs of an assignment. The issue can cause data corruption across call frames. The expected behavior is to revert due to out-of-bounds array access. Version 0.3.8 contains a patch for this issue. | |||||
| CVE-2022-24845 | 1 Vyperlang | 1 Vyper | 2023-08-02 | 7.5 HIGH | 9.8 CRITICAL |
| Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In affected versions, the return of `<iface>.returns_int128()` is not validated to fall within the bounds of `int128`. This issue can result in a misinterpretation of the integer value and lead to incorrect behavior. As of v0.3.0, `<iface>.returns_int128()` is validated in simple expressions, but not complex expressions. Users are advised to upgrade. There is no known workaround for this issue. | |||||
| CVE-2022-24788 | 1 Vyperlang | 1 Vyper | 2023-08-02 | 7.5 HIGH | 9.8 CRITICAL |
| Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. Versions of vyper prior to 0.3.2 suffer from a potential buffer overrun. Importing a function from a JSON interface which returns `bytes` generates bytecode which does not clamp bytes length, potentially resulting in a buffer overrun. Users are advised to upgrade. There are no known workarounds for this issue. | |||||
