"The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as
referenced in the USN-4646-1 advisory.

  - Poppler before 0.66.0 has an integer overflow in Parser::makeStream in Parser.cc. (CVE-2018-21009)

  - The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream
    length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the
    heap, with a size controlled by an attacker, as demonstrated by pdftocairo. (CVE-2019-9959)

  - An issue was discovered in Poppler 0.74.0. There is a heap-based buffer over-read in the function
    PSOutputDev::checkPageSlice at PSOutputDev.cc. (CVE-2019-10871)

  - In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in strncpy from FoFiType1::parse in
    fofi/FoFiType1.cc because it does not ensure the source string has a valid length before making a fixed-
    length copy. It can, for example, be triggered by sending a crafted PDF document to the pdftotext tool. It
    allows an attacker to use a crafted pdf file to cause Denial of Service or an information leak, or
    possibly have unspecified other impact. (CVE-2019-13283)

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