CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32649 – vyper performs double eval of the argument of sqrt
https://notcve.org/view.php?id=CVE-2024-32649
Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the `sqrt` builtin can result in double eval vulnerability when the argument has side-effects. It can be seen that the `build_IR` function of the `sqrt` builtin doesn't cache the argument to the stack. As such, it can be evaluated multiple times (instead of retrieving the value from the stack). No vulnerable production contracts were found. • https://github.com/vyperlang/vyper/security/advisories/GHSA-5jrj-52x8-m64h • CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32648 – vyper default functions don't respect nonreentrancy keys
https://notcve.org/view.php?id=CVE-2024-32648
Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Prior to version 0.3.0, default functions don't respect nonreentrancy keys and the lock isn't emitted. No vulnerable production contracts were found. Additionally, using a lock on a `default` function is a very sparsely used pattern. As such, the impact is low. • https://github.com/vyperlang/vyper/commit/93287e5ac184b53b395c907d40701f721daf8177 https://github.com/vyperlang/vyper/issues/2455 https://github.com/vyperlang/vyper/security/advisories/GHSA-m2v9-w374-5hj9 • CWE-667: Improper Locking •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32647 – vyper performs double eval of raw_args in create_from_blueprint
https://notcve.org/view.php?id=CVE-2024-32647
Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the `create_from_blueprint` builtin can result in a double eval vulnerability when `raw_args=True` and the `args` argument has side-effects. It can be seen that the `_build_create_IR` function of the `create_from_blueprint` builtin doesn't cache the mentioned `args` argument to the stack. As such, it can be evaluated multiple times (instead of retrieving the value from the stack). No vulnerable production contracts were found. • https://github.com/vyperlang/vyper/blob/cedf7087e68e67c7bfbd47ae95dcb16b81ad2e02/vyper/builtins/functions.py#L1847 https://github.com/vyperlang/vyper/security/advisories/GHSA-3whq-64q2-qfj6 • CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32646 – vyper performs double eval of the slice args when buffer from adhoc locations
https://notcve.org/view.php?id=CVE-2024-32646
Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the `slice` builtin can result in a double eval vulnerability when the buffer argument is either `msg.data`, `self.code` or `<address>.code` and either the `start` or `length` arguments have side-effects. It can be easily triggered only with the versions `<0.3.4` as `0.3.4` introduced the unique symbol fence. No vulnerable production contracts were found. Additionally, double evaluation of side-effects should be easily discoverable in client tests. • https://github.com/vyperlang/vyper/security/advisories/GHSA-r56x-j438-vw5m • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32645 – vyper performs incorrect topic logging in raw_log
https://notcve.org/view.php?id=CVE-2024-32645
Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, incorrect values can be logged when `raw_log` builtin is called with memory or storage arguments to be used as topics. A contract search was performed and no vulnerable contracts were found in production. The `build_IR` function of the `RawLog` class fails to properly unwrap the variables provided as topics. Consequently, incorrect values are logged as topics. • https://github.com/vyperlang/vyper/security/advisories/GHSA-xchq-w5r3-4wg3 • CWE-20: Improper Input Validation •
