"The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2020-1074 advisory.

  - 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 Poppler through 0.76.1, there is a heap-based buffer over-read in JPXStream::init in JPEG2000Stream.cc
    via data with inconsistent heights or widths. (CVE-2019-12293)

  - The tiff_document_render() and tiff_document_get_thumbnail() functions in the TIFF document backend in
    GNOME Evince through 3.32.0 did not handle errors from TIFFReadRGBAImageOriented(), leading to
    uninitialized memory use when processing certain TIFF image files. (CVE-2019-11459)

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

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