CVE-2019-3835

It was found that the superexec operator was available in the internal dictionary in ghostscript before 9.27.

MEDIUM 5.5EPSS 2.47%

Does this matter?

Lower severity and a low EPSS score (2.47%). Track it; it rarely justifies an emergency change on its own.

Description

It was found that the superexec operator was available in the internal dictionary in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.
