Ubuntu 18.04 LTS / 20.04 LTS : containerd vulnerabilities (USN-5012-1)

medium Nessus Plugin ID 151830

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5012-1 advisory.

 It was discovered that containerd incorrectly handled file permission changes. If a user or automated system were tricked into launching a specially crafted container image, a remote attacker could change permissions on files on the host filesystem and possibly escalate privileges.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected containerd and / or golang-github-containerd-containerd-dev packages.
