Package : ghostscript
Type : sandbox escape
Remote : Yes
Link : https://security.archlinux.org/AVG-929
The package ghostscript before version 9.27-1 is vulnerable to sandbox

Upgrade to 9.27-1.
The problems have been fixed upstream in version 9.27.
None.
It was found that the superexec operator was available in the internal
dictionary. 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.
It was found that the forceput operator could be extracted from the
DefineResource method using methods similar to the ones described in
