The version of containerd installed on the remote host is prior to 1.4.4-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2023-014 advisory.

  - In containerd (an industry-standard container runtime) before versions 1.3.10 and 1.4.4, containers     launched through containerd's CRI implementation (through Kubernetes, crictl, or any other pod/container     client that uses the containerd CRI service) that share the same image may receive incorrect environment     variables, including values that are defined for other containers. If the affected containers have     different security contexts, this may allow sensitive information to be unintentionally shared. If you are     not using containerd's CRI implementation (through one of the mechanisms described above), you are not     vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same     image which have different environment variables, you are not vulnerable to this issue. If you are not     launching multiple containers or Kubernetes pods from the same image in rapid succession, you have reduced     likelihood of being vulnerable to this issue This vulnerability has been fixed in containerd 1.3.10 and     containerd 1.4.4. Users should update to these versions. (CVE-2021-21334)

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

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:0878-1 advisory.

  - In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in     which access to remapped root allows privilege escalation to real root. When using --userns-remap, if     the root user in the remapped namespace has access to the host filesystem they can modify files under     /var/lib/docker/ that cause writing files with extended privileges. Versions 20.10.3 and     19.03.15 contain patches that prevent privilege escalation from remapped user. (CVE-2021-21284)

  - In Docker before versions 9.03.15, 20.10.3 there is a vulnerability in which pulling an intentionally     malformed Docker image manifest crashes the dockerd daemon. Versions 20.10.3 and 19.03.15 contain patches     that prevent the daemon from crashing. (CVE-2021-21285)

  - In containerd (an industry-standard container runtime) before versions 1.3.10 and 1.4.4, containers     launched through containerd's CRI implementation (through Kubernetes, crictl, or any other pod/container     client that uses the containerd CRI service) that share the same image may receive incorrect environment     variables, including values that are defined for other containers.

Users should update to these versions. (CVE-2021-21334)

  - runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the     vulnerability, an attacker must be able to create multiple containers with a fairly specific mount     configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.
    (CVE-2021-30465)

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

The remote host is affected by the vulnerability described in GLSA-202105-33 (containerd: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in containerd. Please       review the CVE identifiers referenced below for details.
  Impact :

    A local attacker, able to run a malicious container in the same network       namespace as the shim, could possibly escalate privileges. Furthermore,       an attacker could disclose sensitive information.
  Workaround :

    There is no known workaround at this time.

The remote Fedora 33 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-10ce8fcbf1 advisory.
