CVE-2018-16510
Incorrect exec stack handling in the "CS" and "SC" PDF primitives could be used by remote attackers able to supply crafted PDFs to crash the interpreter or possibly have unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
