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.

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
