"The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-4688-1 advisory.

  - JasPer 2.0.12 allows remote attackers to cause a denial of service (heap-based buffer over-read and
    application crash) via a crafted image, related to the jp2_decode function in libjasper/jp2/jp2_dec.c.
    (CVE-2017-9782)

  - An issue was discovered in JasPer 2.0.14. There is a NULL pointer dereference in the function
    ras_putdatastd in ras/ras_enc.c. (CVE-2018-18873)

  - An issue was discovered in JasPer 2.0.14. There is a NULL pointer dereference in the function jp2_decode
    in libjasper/jp2/jp2_dec.c, leading to a denial of service. (CVE-2018-19542)

  - There's a flaw in jasper's jpc encoder in versions prior to 2.0.23. Crafted input provided to jasper by an
    attacker could cause an arbitrary out-of-bounds write. This could potentially affect data confidentiality,
    integrity, or application availability. (CVE-2020-27828)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
