Vulnerabilities in dependencies

Is Apache Guacamole affected by CVE-2023-5129?

No. CVE-2023-5129 (aka CVE-2023-4863) deals specifically with decoding WebP images, not encoding.

You would also receive updates to libwebp from your distribution as the library itself is not bundled within Guacamole. If using our Docker images, the images are automatically rebuilt nightly to bring in updates from the maintainer of the base image (Alpine Linux), and a pull of the latest would give you an updated image.

Is Apache Guacamole affected by CVE-2021-44228?
