"The version of xpdf installed on the remote host is prior to 4.05. It is, therefore, affected by multiple
vulnerabilities as referenced in the SSA:2024-040-01 advisory.

  - XRef::fetch in XRef.cc in Xpdf 4.00 allows remote attackers to cause a denial of service (stack
    consumption) via a crafted pdf file, related to AcroForm::scanField, as demonstrated by pdftohtml. NOTE:
    this might overlap CVE-2018-7453. (CVE-2018-16369)

  - Infinite recursion in AcroForm::scanField in AcroForm.cc in xpdf 4.00 allows attackers to launch denial of
    service via a specific pdf file due to lack of loop checking, as demonstrated by pdftohtml.
    (CVE-2018-7453)

  - XPDF v4.0.4 was discovered to contain a segmentation violation via the component /xpdf/AcroForm.cc:538.
    (CVE-2022-36561)

  - An issue was discovered in Xpdf 4.04. There is a crash in XRef::fetch(int, int, Object*, int) in
    xpdf/XRef.cc, a different vulnerability than CVE-2018-16369 and CVE-2019-16088. (CVE-2022-41844)

  - In Xpdf 4.04 (and earlier), a bad color space object in the input PDF file can cause a divide-by-zero.
    (CVE-2023-2662)

  - In Xpdf 4.04 (and earlier), a PDF object loop in the page label tree leads to infinite recursion and a
    stack overflow. (CVE-2023-2663)

  - In Xpdf 4.04 (and earlier), a PDF object loop in the embedded file tree leads to infinite recursion and a
    stack overflow. (CVE-2023-2664)

  - An excessively large PDF page size (found in fuzz testing, unlikely in normal PDF files) can result in a
    divide-by-zero in Xpdf's text extraction code. This is related to CVE-2022-30524, but the problem here is
    caused by a very large page size, rather than by a very large character coordinate. (CVE-2023-3044)

  - Xpdf 4.04 will deadlock on a PDF object stream whose Length field is itself in another object stream.
    (CVE-2023-3436)

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