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.
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.
