"According to the versions of the docker-engine packages installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :
- containerd is an open source container runtime with an emphasis on simplicity, robustness and portability.
A bug was found in containerd where container root directories and some plugins had insufficiently
restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and
execute programs. When containers included executable programs with extended permission bits (such as
setuid), unprivileged Linux users could discover and execute those programs. When the UID of an
unprivileged Linux user on the host collided with the file owner or group inside a container, the
unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has
been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are
released and may restart containers or update directory permissions to mitigate the vulnerability. Users
unable to update should limit access to the host to trusted users. Update directory permission on
container bundles directories. (CVE-2021-41103)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
