"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3281
advisory.

  - An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying
    crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from
    the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both
    s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively
    developed). (CVE-2022-47950)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
