| CVE-2022-2211 | Med | 0.42 | 6.5 | 0.01 | Jul 12, 2022 | A vulnerability was found in libguestfs. This issue occurs while calculating the greatest possible number of matching keys in the get_keys() function. This flaw leads to a denial of service, either by mistake or malicious actor. | ||
| CVE-2019-14851 | Med | 0.42 | 6.5 | 0.01 | Mar 18, 2021 | 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. | ||
| CVE-2019-14850 | Low | 0.24 | 3.7 | 0.02 | Mar 18, 2021 | 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… | ||
| CVE-2025-47712 | 0.00 | — | 0.00 | Jun 9, 2025 | A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request.
