Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. Arrays can be keyed by a signed integer, while they are defined for unsigned integers only. The typechecker doesn't throw when spotting the usage of an `int` as an index for an array. The typechecker allows the usage of signed integers to be used as indexes to arrays. The vulnerability is present in different forms in all versions, including `0.3.10`. For ints, the 2's complement representation is used. Because the array was declared very large, the bounds checking will pass Negative values will simply be represented as very large numbers. As of time of publication, a fixed version does not exist. There are three potential vulnerability classes: unpredictable behavior, accessing inaccessible elements and denial of service. Class 1: If it is possible to index an array with a negative integer without reverting, this is most likely not anticipated by the developer and such accesses can cause unpredictable behavior for the contract. Class 2: If a contract has an invariant in the form `assert index < x`, the developer will suppose that no elements on indexes `y | y >= x` are accessible. However, by using negative indexes, this can be bypassed. Class 3: If the index is dependent on the state of the contract, this poses a risk of denial of service. If the state of the contract can be manipulated in such way that the index will be forced to be negative, the array access can always revert (because most likely the array won't be declared extremely large). However, all these the scenarios are highly unlikely. Most likely behavior is a revert on the bounds check.
A CWE-129: Improper Validation of Array Index vulnerability exists that could cause local denial-of-service, and potentially kernel execution when a malicious actor with local user access crafts a script/program using an unpredictable index to an IOCTL call in the Foxboro.sys driver.
A CWE-129: Improper validation of an array index vulnerability exists where a specially crafted Ethernet request could result in denial of service or remote code execution.
The affected products are vulnerable to an improper validation of array index, which could allow an attacker to crash the server and remotely execute arbitrary code.
Altair HyperView Player versions 2021.1.0.27 and prior are vulnerable to improper validation of array index vulnerability during processing of H3D files. A DWORD value from a PoC file is extracted and used as an index to write to a buffer, leading to memory corruption.
Akashi is an open source server implementation of the Attorney Online video game based on the Ace Attorney universe. Affected versions of Akashi are subject to a denial of service attack. An attacker can use a specially crafted evidence packet to make an illegal modification, causing a server crash. This can be used to mount a denial-of-service exploit. Users are advised to upgrade. There is no known workaround for this issue.
Possible buffer overflow due to improper validation of array index while processing external DIAG command in Snapdragon Auto, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables
Memory corruption in DSP service due to improper validation of input parameters in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Industrial IOT, Snapdragon Mobile
An improper array index validation vulnerability exists in the JPEG-JFIF Scan header parser functionality of Accusoft ImageGear 19.10. A specially-crafted file can lead to an out-of-bounds write and potential code exectuion. An attacker can provide a malicious file to trigger this vulnerability.
Improper Validation of Array Index in GitHub repository radareorg/radare2 prior to 5.6.8. This vulnerability is heap overflow and may be exploitable. For more general description of heap buffer overflow, see [CWE](https://cwe.mitre.org/data/definitions/122.html).
