The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1689-1 advisory.

  - The x/crypto/ssh package before 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an     attacker to panic an SSH server. (CVE-2021-43565)

  - containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in     containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd's CRI     implementation on Linux with a specially-crafted image configuration could gain access to read-only copies     of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container     setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation. This bug has been     fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.
    (CVE-2022-23648)

  - Moby is an open-source project created by Docker to enable and accelerate software containerization. A bug     was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started 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)`. Normally, when executable programs have specified permitted file capabilities, otherwise     unprivileged users and processes can execute those programs and gain the specified file capabilities up to     the bounding set. Due to this bug, containers which included executable programs with inheritable file     capabilities allowed otherwise unprivileged users and processes to additionally gain these inheritable     file capabilities up to the container's bounding set. Containers which use Linux users and groups to     perform privilege separation inside the container are most directly impacted. 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 Moby (Docker Engine) 20.10.14. Running containers     should be stopped, deleted, and recreated for the inheritable capabilities to be reset. This fix changes     Moby (Docker Engine) behavior such that containers are started with a more typical Linux environment. As a     workaround, the entry point of a container can be modified to use a utility like `capsh(1)` to drop     inheritable capabilities prior to the primary process starting. (CVE-2022-24769)

  - 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)

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

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2022:7457 advisory.

  - golang: net/http/httputil: panic due to racy read of persistConn after handler panic (CVE-2021-36221)

  - opencontainers: OCI manifest and index parsing confusion (CVE-2021-41190)

  - cri-o: memory exhaustion on the node when access to the kube api (CVE-2022-1708)

  - golang: crash in a golang.org/x/crypto/ssh server (CVE-2022-27191)

  - runc: incorrect handling of inheritable capabilities (CVE-2022-29162)

  - buildah: possible information disclosure and modification (CVE-2022-2990)

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

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:7457 advisory.

  - 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)

  - Go before 1.15.15 and 1.16.x before 1.16.7 has a race condition that can lead to a net/http/httputil     ReverseProxy panic upon an ErrAbortHandler abort. (CVE-2021-36221)

  - The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution     of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone     was used to determine the type of document during push and pull operations. Documents that contain both     manifests and layers fields could be interpreted as either a manifest or an index in the absence of an     accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a     client may interpret the resulting content differently. The OCI Distribution Specification has been     updated to require that a mediaType value present in a manifest or index match the Content-Type header     used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type     header and reject an ambiguous document that contains both manifests and layers fields or manifests     and config fields if they are unable to update to version 1.0.1 of the spec. (CVE-2021-41190)

  - 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)

  - An incorrect handling of the supplementary groups in the Buildah container engine might lead to the     sensitive information disclosure or possible data modification if an attacker has direct access to the     affected container where supplementary groups are used to set access permissions and is able to execute a     binary code in that container. (CVE-2022-2990)
