"The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-3838-1 advisory.

    It was discovered that LibRaw incorrectly handled photo files. If a user or automated system were tricked
    into processing a specially crafted photo file, a remote attacker could cause applications linked against
    LibRaw 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.

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