CVE-2018-19475
psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
