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.

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

  - 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)

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)

This update for mupdf fixes the following security issue :

  - CVE-2018-1000051: Prevent use after free 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 (bsc#1080531).

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.

Two vulnerabilities were discovered in MuPDF, a PDF, XPS, and e-book viewer, which may result in denial of service or remote code execution. An attacker can craft a PDF document which, when opened in the victim host, might consume vast amounts of memory, crash the program, or, in some cases, execute code in the context in which the application is running.
