"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0267 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-33198:
    In Go before 1.15.13 and 1.16.x before 1.16.5, there can be a panic for a large exponent to the
    math/big.Rat SetString or UnmarshalText method.

    CVE-2021-4024:
    A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual
    machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is
    accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an
    attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making
    private services on the VM accessible to the network. This issue could be also used to interrupt the
    host's services by forwarding all ports to the VM.

    CVE-2024-9676:
    A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the
    containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service
    via OOM kill when running a malicious image using an automatically assigned user namespace
    (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the
    container, but does not properly validate if that file is a symlink, which can be used to cause the
    library to read an arbitrary file on the host.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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