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

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and     below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large     number of chunks. If an application makes use of the request.read() method in an endpoint, it may be     possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1     second) while processing the request. This could potentially lead to DoS as the server would be unable to     handle other requests during that time. This issue is fixed in version 3.13.3. (CVE-2025-69229)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20204-1 advisory.

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8032-1 advisory.

    Charles Chan discovered that AIOHTTP incorrectly handled the decompression of compressed requests. A     remote attacker could possibly use this issue to cause a denial of service. This issue was only addressed     in Ubuntu 25.10. (CVE-2025-69223)

    Thomas Rinsma discovered that AIOHTTP incorrectly handled non-ASCII characters in HTTP headers. A remote     attacker could possibly use this issue to perform a request smuggling attack to bypass certain proxy     protections. This issue was only addressed in Ubuntu 22.04 LTS, Ubuntu 24.04 LTS and Ubuntu 25.10.
