Fixed In Version: ghostcript 9.21
Doc Type: If docs needed, set a value
Doc Text:
Ghostscript did not honor the -dSAFER option when executing the "status" instruction, which can be used to retrieve information such as a file's existence and size. A specially crafted postscript document could use this flow to gain information on the targeted system's filesystem content.

Description Sam Fowler 2018-06-05 05:42:20 UTC
Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which can allow remote attackers to determine the existence and size of arbitrary files.
