The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5841-1 advisory.

  - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in LibTIFF through 4.0.10 mishandle Integer Overflow     checks because they rely on compiler behavior that is undefined by the applicable C standards. This can,     for example, lead to an application crash. (CVE-2019-14973)

  - tif_getimage.c in LibTIFF through 4.0.10, as used in GDAL through 3.0.1 and other products, has an integer     overflow that potentially causes a heap-based buffer overflow via a crafted RGBA image, related to a     Negative-size-param condition. (CVE-2019-17546)

  - An integer overflow flaw was found in libtiff that exists in the tif_getimage.c file. This flaw allows an     attacker to inject and execute arbitrary code when a user opens a crafted TIFF file. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35523)

  - A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's     TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from     this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35524)

  - A vulnerability was found in LibTIFF. It has been classified as critical. This affects the function     TIFFReadRGBATileExt of the file libtiff/tif_getimage.c. The manipulation leads to integer overflow. It is     possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
    The name of the patch is 227500897dfb07fb7d27f7aa570050e62617e3be. It is recommended to apply a patch to     fix this issue. The identifier VDB-213549 was assigned to this vulnerability. (CVE-2022-3970)

  - processCropSelections in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based buffer overflow (e.g.,     WRITE of size 307203) via a crafted TIFF image. (CVE-2022-48281)

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