Multiple vulnerabilities were discovered in MuPDF, a PDF, XPS, and e-book
viewer which could result in denial of service or the execution of
arbitrary code if malformed documents are opened.

For the stable distribution (stretch), these problems have been fixed in
version 1.9a+ds1-4+deb9u4.

We recommend that you upgrade your mupdf packages.
