The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3921-1 advisory.

It was discovered that XMLTooling incorrectly handled certain XML files with invalid data. An attacker     could use this issue to cause XMLTooling to crash, resulting in a denial of service.

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.
