In Artifex MuPDF 1.12.0, the pdf_read_new_xref function in pdf/pdf-xref.c allows remote attackers to cause a denial of service (segmentation violation and application crash) via a crafted pdf file.

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

  - In Artifex MuPDF 1.12.0, the pdf_read_new_xref function in pdf/pdf-xref.c allows remote attackers to cause     a denial of service (segmentation violation and application crash) via a crafted pdf file. (CVE-2018-6192)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Artifex Mupdf version 1.12.0 contains a Use After Free vulnerability in fz_keep_key_storable that can
    result in DOS / Possible code execution. This attack appear to be exploitable via Victim opens a specially
    crafted PDF. (CVE-2018-1000051)

  - Heap-based buffer overflow in the ensure_solid_xref function in pdf/pdf-xref.c in Artifex MuPDF 1.12.0
    allows a remote attacker to potentially execute arbitrary code via a crafted PDF file, because xref
    subsection object numbers are unrestricted. (CVE-2017-17858)

  - In MuPDF 1.12.0, there is an infinite loop vulnerability and application hang in the pdf_parse_array
    function (pdf/pdf-parse.c) because EOF is not considered. Remote attackers could leverage this
    vulnerability to cause a denial of service via a crafted pdf file. (CVE-2018-5686)

  - In Artifex MuPDF 1.12.0, there is a heap-based buffer overflow vulnerability in the do_pdf_save_document
    function in the pdf/pdf-write.c file. Remote attackers could leverage the vulnerability to cause a denial
    of service via a crafted pdf file. (CVE-2018-6187)

  - In Artifex MuPDF 1.12.0, the pdf_read_new_xref function in pdf/pdf-xref.c allows remote attackers to cause
    a denial of service (segmentation violation and application crash) via a crafted pdf file. (CVE-2018-6192)

Several minor issues have been fixed in mupdf, a lightweight PDF viewer tailored for display of high quality anti-aliased graphics.

CVE-2018-5686

In MuPDF, there was an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF not having been considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted PDF file.

CVE-2019-6130

MuPDF had a SEGV in the function fz_load_page of the fitz/document.c file, as demonstrated by mutool. This was related to page-number mishandling in cbz/mucbz.c, cbz/muimg.c, and svg/svg-doc.c.

CVE-2018-6192

In MuPDF, the pdf_read_new_xref function in pdf/pdf-xref.c allowed remote attackers to cause a denial of service (segmentation violation and application crash) via a crafted PDF file.

For Debian 8 'Jessie', these problems have been fixed in version 1.5-1+deb8u6.

We recommend that you upgrade your mupdf packages.

The remote host is affected by the vulnerability described in GLSA-201811-15 (MuPDF: Multiple vulnerabilities)

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

    A remote attacker, by enticing a user to process a specially crafted       file, could possibly execute arbitrary code, cause a Denial of Service       condition, or have other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities were discovered in MuPDF, a PDF, XPS, and e-book viewer which could result in denial of service or the execution of arbitrary code if malformed documents are opened.

CVE-2018-6192 CVE-2018-6544 CVE-2018-1000051 CVE-2018-6187

This update for mupdf fixes several issues.

These security issues were fixed :

  - CVE-2018-6187: Prevent heap-based buffer overflow in the     do_pdf_save_document function. Remote attackers could     leverage the vulnerability to cause a denial of service     via a crafted pdf file (bsc#1077407).

  - CVE-2018-6544: pdf_load_obj_stm could have referenced     the object stream recursively and therefore run out of     error stack, which allowed remote attackers to cause a     denial of service via a crafted PDF document     (bsc#1079100).

  - CVE-2018-6192: The pdf_read_new_xref function allowed     remote attackers to cause a denial of service     (segmentation violation and application crash) via a     crafted pdf file (bsc#1077755).
