"The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-4587-1 advisory.

    Nicolas Ruff discovered that iTALC had buffer overflows, divide-by-zero errors and didn't check malloc
    return values. A remote attacker could use these issues to cause a denial of service or possibly execute
    arbitrary code. (CVE-2014-6051, CVE-2014-6052, CVE-2014-6053, CVE-2014-6054, CVE-2014-6055)

    Josef Gajdusek discovered that iTALC had heap-based buffer overflow vulnerabilities. A remote attacker
    could used these issues to cause a denial of service or possibly execute arbitrary code. (CVE-2016-9941,
    CVE-2016-9942)

    It was discovered that iTALC had an out-of-bounds write, multiple heap out-of-bounds writes, an infinite
    loop, improper initializations, and null pointer vulnerabilities. A remote attacker could used these
    issues to cause a denial of service or possibly execute arbitrary code. (CVE-2018-15127, CVE-2018-20019,
    CVE-2018-20020, CVE-2018-20021, CVE-2018-20022, CVE-2018-20023, CVE-2018-20024, CVE-2018-20748,
