CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 1CVE-2022-24845 – Integer bounds error in Vyper
https://notcve.org/view.php?id=CVE-2022-24845
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. • https://github.com/vyperlang/vyper/commit/049dbdc647b2ce838fae7c188e6bb09cf16e470b https://github.com/vyperlang/vyper/security/advisories/GHSA-j2x6-9323-fp7h • CWE-190: Integer Overflow or Wraparound •
CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-24788 – Buffer overflow in Vyper
https://notcve.org/view.php?id=CVE-2022-24788
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. • https://github.com/vyperlang/vyper/commit/049dbdc647b2ce838fae7c188e6bb09cf16e470b https://github.com/vyperlang/vyper/security/advisories/GHSA-4mrx-6fxm-8jpg • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-24787 – Incorrect Comparison in Vyper
https://notcve.org/view.php?id=CVE-2022-24787
Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. In version 0.3.1 and prior, bytestrings can have dirty bytes in them, resulting in the word-for-word comparisons giving incorrect results. Even without dirty nonzero bytes, two bytestrings can compare to equal if one ends with `"\x00"` because there is no comparison of the length. A patch is available and expected to be part of the 0.3.2 release. There are currently no known workarounds. • https://github.com/vyperlang/vyper/commit/2c73f8352635c0a433423a5b94740de1a118e508 https://github.com/vyperlang/vyper/security/advisories/GHSA-7vrm-3jc8-5wwm • CWE-697: Incorrect Comparison •
