Slackware Linux 15.0 / current xpdf Multiple Vulnerabilities (SSA:2024-040-01)

medium Nessus Plugin ID 190377


The remote Slackware Linux host is missing a security update to xpdf.


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 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 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.

- XPDF v4.0.4 was discovered to contain a segmentation violation via the component /xpdf/

- An issue was discovered in Xpdf 4.04. There is a crash in XRef::fetch(int, int, Object*, int) in xpdf/, 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.

- 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.

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


Upgrade the affected xpdf package.
