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.
