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

  - Ceph is a distributed object, block, and file storage platform. In versions 17.2.7, 18.2.1 through 18.2.4,
    and 19.0.0 through 19.2.2, an unprivileged user can escalate to root privileges in a ceph-fuse mounted
    CephFS by chmod 777 a directory owned by root to gain access. The result of this is that a user could
    read, write and execute to any directory owned by root as long as they chmod 777 it. This impacts
    confidentiality, integrity, and availability. It is patched in versions 17.2.8, 18.2.5, and 19.2.3.
