The xps_true_callback_glyph_name function in xps/xpsttf.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (Segmentation Violation and application crash) via a crafted file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
