Kerentanan Improper Restriction of Operations within the Bounds of a Memory Buffer pada vyperlang vyper. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In versions 0.3.10 and earlier, the bounds check for slices does not account for the ability for start + length to overflow when the values aren't literals. If a slice() function uses a non-literal argument for the start or length variable, this creates the ability for an attacker to overflow the bounds check. This issue can be used to do OOB access to storage, memory or calldata addresses. It can also be used to corrupt the length slot of the respective array.
