"The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2020-5003 advisory.

  - In httplib2 before version 0.18.0, an attacker controlling unescaped part of uri for
    `httplib2.Http.request()` could change request headers and body, send additional hidden requests to same
    server. This vulnerability impacts software that uses httplib2 with uri constructed by string
    concatenation, as opposed to proper urllib building with escaping. This has been fixed in 0.18.0.
