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

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4971-1 advisory.

    It was discovered that libwebp incorrectly handled certain malformed images. If a user or automated system     were tricked into opening a specially crafted image file, a remote attacker could use this issue to cause     libwebp to crash, resulting in a denial of service, or possibly execute arbitrary code.

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