EulerOS 2.0 SP10 : docker-engine (EulerOS-SA-2022-1658)

medium Nessus Plugin ID 160677

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using '--userns-remap', if the root user in the remapped namespace has access to the host filesystem they can modify files under '/var/lib/docker/<remapping>' that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user. (CVE-2021-21284)

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.

Solution

Update the affected docker-engine packages.
