Ubuntu-image is a tool that generates system images. Images are typically composed of Ubuntu software and application code, and without regular maintenance and updates they can become vulnerable.

An image's author or maintainer is the sole party responsible for its security. Image authors should be diligent and keep the software inside their images up-to-date with the latest releases, security patches, and security measures.

Any vulnerabilities found in an image should be reported to the image's author or maintainer.

We support the last version published in the latest/stable channel of the Snapstore.

Previous major versions (1.X and 2.X) are not supported.

To report a security issue, file a Private Security Report with a description of the issue, the steps you took to create the issue, affected versions, and, if known, mitigations for the issue.

The Ubuntu Security disclosure and embargo policy contains more information about what you can expect when you contact us and what we expect from you.
