An issue was discovered in Docker Engine before 19.03.11. An attacker in a container, with the CAP_NET_RAW capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain sensitive information, or cause a denial of service.

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2020-5728 advisory.

  - An issue was discovered in Docker Engine before 19.03.11. An attacker in a container, with the CAP_NET_RAW     capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain     sensitive information, or cause a denial of service. (CVE-2020-13401)

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

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has docker-ce packages installed that are affected by multiple vulnerabilities:

  - Lack of content verification in Docker-CE (Also known as Moby) versions 1.12.6-0, 1.10.3, 17.03.0,     17.03.1, 17.03.2, 17.06.0, 17.06.1, 17.06.2, 17.09.0, and earlier allows a remote attacker to cause a     Denial of Service via a crafted image layer payload, aka gzip bombing. (CVE-2017-14992)

  - The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block     /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are     used) by leveraging Docker container access to write a scsi remove-single-device line to     /proc/scsi/scsi, aka SCSI MICDROP. (CVE-2017-16539)

  - libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than     ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall     arguments could bypass intended access restrictions by specifying a single matching argument.
    (CVE-2017-18367)

  - The default OCI linux spec in oci/defaults{_linux}.go in Docker/Moby from 1.11 to current does not block     /proc/acpi pathnames. The flaw allows an attacker to modify host's hardware like enabling/disabling     bluetooth or turning up/down keyboard brightness. (CVE-2018-10892)

  - In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker cp' command are vulnerable to a     symlink-exchange attack with Directory Traversal, giving attackers arbitrary read-write access to the host     filesystem with root privileges, because daemon/archive.go does not do archive operations on a frozen     filesystem (or from within a chroot). (CVE-2018-15664)

  - Docker Engine before 18.09 allows attackers to cause a denial of service (dockerd memory consumption) via     a large integer in a --cpuset-mems or --cpuset-cpus value, related to daemon/daemon_unix.go,     pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go. (CVE-2018-20699)

  - In Docker before 18.09.4, an attacker who is capable of supplying or manipulating the build path for the     docker build command would be able to gain command execution. An issue exists in the way docker build     processes remote git URLs, and results in command injection into the underlying git clone command,     leading to code execution in the context of the user executing the docker build command. This occurs     because git ref can be misinterpreted as a flag. (CVE-2019-13139)

  - In Docker CE and EE before 18.09.8 (as well as Docker EE before 17.06.2-ee-23 and 18.x before     18.03.1-ee-10), Docker Engine in debug mode may sometimes add secrets to the debug log. This applies to a     scenario where docker stack deploy is run to redeploy a stack that includes (non external) secrets. It     potentially applies to other API users of the stack API if they resend the secret. (CVE-2019-13509)

  - runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite     the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a     command as root within one of these types of containers: (1) a new container with an attacker-controlled     image, or (2) an existing container, to which the attacker previously had write access, that can be     attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
    (CVE-2019-5736)

The remote host is affected by the vulnerability described in GLSA-202008-15 (Docker: Information disclosure)

    It was found that Docker created network bridges which by default accept       IPv6 router advertisements.
  Impact :

    An attacker who gained access to a container with CAP_NET_RAW capability       may be able to to spoof router advertisements, resulting in information       disclosure or denial of service.
  Workaround :

    There is no known workaround at this time.

According to the version of the docker-engine packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :
