Vulnerability CVE-2017-14685

Vulnerability Name:

CVE-2017-14685 (CCN-132466)

Assigned:

2017-09-22

Published:

Updated:

Summary:

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.
