CVE-2019-14975
Artifex MuPDF before 1.16.0 has a heap-based buffer over-read in fz_chartorune in fitz/string.c because pdf/pdf-op-filter.c does not check for a missing string.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
