"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3620 advisory.

  - Uncontrolled Recursion in pdfinfo, and pdftops in poppler 0.89.0 allows remote attackers to cause a denial
    of service via crafted input. (CVE-2020-23804)

  - In Poppler 22.07.0, PDFDoc::savePageAs in PDFDoc.c callows attackers to cause a denial-of-service
    (application crashes with SIGABRT) by crafting a PDF file in which the xref data structure is mishandled
    in getCatalog processing. Note that this vulnerability is caused by the incomplete patch of
    CVE-2018-20662. (CVE-2022-37050)

  - An issue was discovered in Poppler 22.07.0. There is a reachable abort which leads to denial of service
    because the main function in pdfunite.cc lacks a stream check before saving an embedded file.
    (CVE-2022-37051)

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