A vulnerability exists in the garbage collection mechanism of atomic-openshift. An attacker able spoof the UUID of a valid object from another namespace is able to delete children of those objects. Versions 3.6, 3.7, 3.8, 3.9, 3.10, 3.11 and 4.1 are affected.

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5634 advisory.

  - atomic-openshift: cross-namespace owner references can trigger deletions of valid children (CVE-2019-3884)

  - kubernetes: Ceph RBD adminSecrets exposed in logs when loglevel >= 4 (CVE-2020-8566)

  - containerd: credentials leak during image pull (CVE-2020-15157)

  - python-rsa: bleichenbacher timing oracle attack against RSA decryption (CVE-2020-25658)

  - golang: math/big: panic during recursive division of very large numbers (CVE-2020-28362)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5634 advisory.
