More information:

Multiple vulnerabilities have been found in MuPDF, a PDF file viewer, which may result in denial of service or the execution of arbitrary code.

• CVE-2017-14685, CVE-2017-14686, and CVE-2017-14687

  WangLin discovered that a crafted .xps file can crash MuPDF and potentially execute arbitrary code in several ways, since the application makes unchecked assumptions on the entry format.

• CVE-2017-15587

  Terry Chia and Jeremy Heng discovered an integer overflow that can cause arbitrary code execution via a crafted .pdf file.

For the stable distribution (stretch), these problems have been fixed in version 1.9a+ds1-4+deb9u1.

We recommend that you upgrade your mupdf packages.
