Description Aleksandr Wagner (Kivak) 2017-09-23 15:43:35 UTC

CVE-2017-14685 (https://nvd.nist.gov/vuln/detail/CVE-2017-14685):

Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file, related to "Data from Faulting Address controls Branch Selection starting at mupdf+0x000000000016aa61" on Windows. This occurs because xps_load_links_in_glyphs in xps/xps-link.c does not verify that an xps font could be loaded.

My mistake, this vulnerability is Windows only.
