"The remote NewStart CGSL host, running version MAIN 7.02, has containerd packages installed that are affected by
multiple vulnerabilities:

  - containerd is an open-source container runtime. In versions prior to 1.7.33, 2.3.2, 2.2.5, 2.1.9, and
    2.0.10 the CRI plugin propagates labels from an image config (LABEL instruction in Dockerfile) to a
    container without validation. This may result in executing an arbitrary command on the host, via a plugin
    that consumes container labels for some operations. This issue has been fixed in versions 1.7.33, 2.3.2,
    2.2.5, 2.1.9, and 2.0.10. (CVE-2026-53488)

  - containerd is an open-source container runtime. Versions 1.7.28 and below, 2.0.0-beta.0 through 2.0.6,
    2.1.0-beta.0 through 2.1.4, and 2.2.0-beta.0 through 2.2.0-rc.1 contain a bug in the CRI Attach
    implementation where a user can exhaust memory on the host due to goroutine leaks. This issue is fixed in
    versions 1.7.29, 2.0.7, 2.1.5 and 2.2.0. To workaround this vulnerability, users can set up an admission
    controller to control accesses to pods/attach resources. (CVE-2025-64329)

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