When the isula cp command is used to copy files from a container to a host machine and the container is controlled by an attacker, the attacker can escape the container.

According to the versions of the iSulad package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - iSulad uses the lcr+lxc runtime (default) to run malicious images, which can cause DOS. (CVE-2021-33634)

  - When malicious images are pulled by isula pull, attackers can execute arbitrary code. (CVE-2021-33635)

  - When the isula load command is used to load malicious images, attackers can execute arbitrary code.
    (CVE-2021-33636)

  - When the isula export command is used to export a container to an image and the container is controlled by     an attacker, the attacker can escape the container. (CVE-2021-33637)

  - When the isula cp command is used to copy files from a container to a host machine and the container is     controlled by an attacker, the attacker can escape the container. (CVE-2021-33638)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
