Package        : mupdf
CVE ID         : CVE-2017-14685 CVE-2017-14686 CVE-2017-14687 CVE-2017-15587
Debian Bug     : 877379 879055

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.
