"The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-5974-1 advisory.

  - In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage
    function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because
    the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
    (CVE-2018-20184)

  - In GraphicsMagick 1.3.31, the ReadDIBImage function of coders/dib.c has a vulnerability allowing a crash
    and denial of service via a dib file that is crafted to appear with direct pixel values and also
    colormapping (which is not available beyond 8-bits/sample), and therefore lacks indexes initialization.
    (CVE-2018-20189)

  - In GraphicsMagick 1.3.27, there is an infinite loop and application hang in the ReadBMPImage function
    (coders/bmp.c). Remote attackers could leverage this vulnerability to cause a denial of service via an
    image file with a crafted bit-field mask value. (CVE-2018-5685)

  - In GraphicsMagick 1.3.28, there is a divide-by-zero in the ReadMNGImage function of coders/png.c. Remote
    attackers could leverage this vulnerability to cause a crash and denial of service via a crafted mng file.
    (CVE-2018-9018)

  - In GraphicsMagick 1.4 snapshot-20190322 Q8, there is a heap-based buffer over-read in the function
    ReadMIFFImage of coders/miff.c, which allows attackers to cause a denial of service or information
    disclosure via an RLE packet. (CVE-2019-11006)

  - GraphicsMagick through 1.3.35 has a heap-based buffer overflow in ReadMNGImage in coders/png.c.
    (CVE-2020-12672)

  - In GraphicsMagick, a heap buffer overflow was found when parsing MIFF. (CVE-2022-1270)

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