Description Andrej Nemec 2017-07-27 12:51:16 UTC 
The xps_select_font_encoding function in xps/xpsfont.c in Artifex Ghostscript GhostXPS 9.22 allows attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document, related to the xps_encode_font_char_imp function.
