The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Internationalized Domain Names in Applications (IDNA) for Python provides support for Internationalized     Domain Names in Applications (IDNA) and Unicode IDNA Compatibility Processing. In versions prior to 3.15,     payloads such as `\u0660 * N` or `\u30fb * N + \u6f22` utilize the `valid_contexto` function prior     to length rejection, and for high values of `N` will take a long time to process. This is the same issue     as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. A specially crafted     argument to the `idna.encode()` function could consume significant resources. This may lead to a denial-     of-service. Starting in version 3.14, the function rejects long inputs as soon as practicable prior to any     further processing to minimize resource consumption. In version 3.15, this approach was extended to lesser     used alternate functions (i.e. per-label conversions and codec support). A workaround is available. Domain     names cannot exceed 253 characters in length. If this length limit is enforced prior to passing the domain     to the `idna.encode()` function, it should no longer consume significant resources. This is triggered by     arbitrarily large inputs that would not occur in normal usage, but may be passed to the library assuming     there is no preliminary input validation by the higher-level application. (CVE-2026-45409)
