- ------------------------------------------------------------------------- Debian Security Advisory DSA-4006-1 security@debian.org https://www.debian.org/security/ October 24, 2017 https://www.debian.org/security/faq - ------------------------------------------------------------------------- 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.
