Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote attackers to cause a denial of service (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.

  - Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote     attackers to cause a denial of service (crash) via a crafted PDF file. (CVE-2016-6265)

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:

  - Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote
    attackers to cause a denial of service (crash) via a crafted PDF file. (CVE-2016-6265)

  - Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote
    attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array.
    (CVE-2016-6525)

The remote host is affected by the vulnerability described in GLSA-201702-12 (MuPDF: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted PDF       document using MuPDF possibly resulting in the execution of arbitrary       code, with the privileges of the process, or a Denial of Service       condition.
  Workaround :

    There is no known workaround at this time.

Tobias Kortkamp reports :

Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array.

Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote attackers to cause a denial of service (crash) via a crafted PDF file.

Two vulnerabilities were discovered in MuPDF, a lightweight PDF viewer. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2016-6265     Marco Grassi discovered a use-after-free vulnerability     in MuPDF. An attacker can take advantage of this flaw to     cause an application crash (denial-of-service), or     potentially to execute arbitrary code with the     privileges of the user running MuPDF, if a specially     crafted PDF file is processed.

  - CVE-2016-6525     Yu Hong and Zheng Jihong discovered a heap overflow     vulnerability within the pdf_load_mesh_params function,     allowing an attacker to cause an application crash     (denial-of-service), or potentially to execute arbitrary     code with the privileges of the user running MuPDF, if a     specially crafted PDF file is processed.

This update for mupdf fixes the following issues :
