| CVE-2022-0618 | 1 Apple | 1 Swiftnio Http\/2 | 2024-11-21 | 7.5 High |
| A program using swift-nio-http2 is vulnerable to a denial of service attack, caused by a network peer sending a specially crafted HTTP/2 frame. This vulnerability is caused by a logical error when parsing a HTTP/2 HEADERS or HTTP/2 PUSH_PROMISE frame where the frame contains padding information without any other data. This logical error caused confusion about the size of the frame, leading to a parsing error. This parsing error immediately crashes the entire process. Sending a HEADERS frame or PUSH_PROMISE frame with HTTP/2 padding information does not require any special permission, so any HTTP/2 connection peer may send such a frame. For clients, this means any server to which they connect may launch this attack. For servers, anyone they allow to connect to them may launch such an attack. The attack is low-effort: it takes very little resources to send an appropriately crafted frame. The impact on availability is high: receiving the frame immediately crashes the server, dropping all in-flight connections and causing the service to need to restart. It is straightforward for an attacker to repeatedly send appropriately crafted frames, so attackers require very few resources to achieve a substantial denial of service. The attack does not have any confidentiality or integrity risks in and of itself: swift-nio-http2 is parsing the frame in memory-safe code, so the crash is safe. However, sudden process crashes can lead to violations of invariants in services, so it is possible that this attack can be used to trigger an error condition that has confidentiality or integrity risks. The risk can be mitigated if untrusted peers can be prevented from communicating with the service. This mitigation is not available to many services. The issue is fixed by rewriting the parsing code to correctly handle the condition. The issue was found by automated fuzzing by oss-fuzz. | ||||
| CVE-2020-9861 | 1 Apple | 1 Swift | 2024-11-21 | 7.5 High |
| A stack overflow issue existed in Swift for Linux. The issue was addressed with improved input validation for dealing with deeply nested malicious JSON input. | ||||
| CVE-2020-36486 | 4 Apple, Blackberry, Google and 1 more | 4 Iphone Os, Blackberry Os, Android and 1 more | 2024-11-21 | 6.1 Medium |
| Swift File Transfer Mobile v1.1.2 and below was discovered to contain a cross-site scripting (XSS) vulnerability via the 'path' parameter of the 'list' and 'download' exception-handling. | ||||
| CVE-2019-9512 | 6 Apache, Apple, Canonical and 3 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2024-11-21 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-8849 | 1 Apple | 1 Swiftnio Ssl | 2024-11-21 | 9.8 Critical |
| The issue was addressed by signaling that an executable stack is not required. This issue is fixed in SwiftNIO SSL 2.4.1. A SwiftNIO application using TLS may be able to execute arbitrary code. | ||||
| CVE-2019-8790 | 1 Apple | 1 Swift | 2024-11-21 | 5.5 Medium |
| This issue was addresses by updating incorrect URLSession file descriptors management logic to match Swift 5.0. This issue is fixed in Swift 5.1.1 for Ubuntu. Incorrect management of file descriptors in URLSession could lead to inadvertent data disclosure. | ||||
| CVE-2018-4281 | 1 Apple | 1 Swiftnio | 2024-11-21 | N/A |
| In SwiftNIO before 1.8.0, a buffer overflow was addressed with improved size validation. | ||||
| CVE-2018-4220 | 1 Apple | 1 Swift | 2024-11-21 | N/A |
| An issue was discovered in certain Apple products. Swift before 4.1.1 Security Update 2018-001 is affected. The issue involves the "Swift for Ubuntu" component. It allows attackers to execute arbitrary code in a privileged context because write and execute permissions are enabled during library loading. | ||||
