"The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2022-7469 advisory.

  - The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to
    crash a server in certain circumstances involving AddHostKey. (CVE-2022-27191)

  - runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug
    was found in runc prior to version 1.1.2 where `runc exec --cap` created processes with non-empty
    inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with
    inheritable file capabilities to elevate those capabilities to the permitted set during execve(2). This
    bug did not affect the container security sandbox as the inheritable set never contained more capabilities
    than were included in the container's bounding set. This bug has been fixed in runc 1.1.2. This fix
    changes `runc exec --cap` behavior such that the additional capabilities granted to the process being
    executed (as specified via `--cap` arguments) do not include inheritable capabilities. In addition, `runc
    spec` is changed to not set any inheritable capabilities in the created example OCI spec (`config.json`)
    file. (CVE-2022-29162)

  - A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with
    access to the Kube API. The ExecSync request runs commands in a container and logs the output of the
    command. This output is then read by CRI-O after command execution, and it is read in a manner where the
    entire file corresponding to the output of the command is read in. Thus, if the output of the command is
    large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of
    the command. The highest threat from this vulnerability is system availability. (CVE-2022-1708)

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