CVE-2018-19477
psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a JBIG2Decode type confusion.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
