Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-1650 advisory.- A malicious container image can consume an unbounded amount of memory when being pulled to a container runtime host, such as Red Hat Enterprise Linux using podman, or OpenShift Container Platform. An attacker can use this flaw to trick a user, with privileges to pull container images, into crashing the process responsible for pulling the image. This flaw affects containers-image versions before 5.2.0.
(CVE-2020-1702)
- runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.) (CVE-2019-19921)
- A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite existing files in volumes, even if they are mounted as read-only. When a user runs a malicious container or a container based on a malicious image with an attached volume that is used for the first time, it is possible to trigger the flaw and overwrite files in the volume.This issue was introduced in version 1.6.0.
(CVE-2020-1726)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
