本ページは nbdkit_project nbdkit に影響する公開済み CVE（NVD の CPE 経由で関連付け）を列挙します。各行に深刻度指標・概要・公開日が含まれます。
| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2025-47712 | A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service. | [email protected] | 6.5 | 0.36% | 2025-06-09 | 2026-06-17 |
| CVE-2025-47711 | There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-of-service. | [email protected] | 6.5 | 0.31% | 2025-06-09 | 2026-06-17 |
| CVE-2021-3716 | A flaw was found in nbdkit due to to improperly caching plaintext state across the STARTTLS encryption boundary. A MitM attacker could use this flaw to inject a plaintext NBD_OPT_STRUCTURED_REPLY before proxying everything else a client sends to the server, potentially leading the client to terminate the NBD session. The highest threat from this vulnerability is to system availability. | [email protected] | 3.1 | 0.56% | 2022-03-02 | 2026-06-17 |
| CVE-2019-14851 | A denial of service vulnerability was discovered in nbdkit. A client issuing a certain sequence of commands could possibly trigger an assertion failure, causing nbdkit to exit. This issue only affected nbdkit versions 1.12.7, 1.14.1, and 1.15.1. | [email protected] | 6.5 | 0.99% | 2021-03-18 | 2026-06-16 |
| CVE-2019-14850 | A denial of service vulnerability was discovered in nbdkit 1.12.7, 1.14.1 and 1.15.1. An attacker could connect to the nbdkit service and cause it to perform a large amount of work in initializing backend plugins, by simply opening a connection to the service. This vulnerability could cause resource consumption and degradation of service in nbdkit, depending on the plugins configured on the server-side. | [email protected] | 3.7 | 1.60% | 2021-03-18 | 2026-06-16 |
