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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202409-25 (Xpdf: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Xpdf. Please review the CVE identifiers referenced below     for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

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

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.
