Descriptions

psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977.

psi/zfile.c en Artifex Ghostscript en versiones anteriores a la 9.21rc1 permite el comando status incluso si se emplea -dSAFER, lo que podría permitir que atacantes remotos determinen la existencia y tamaño de archivos arbitrarios. Este problema es similar a CVE-2016-7977.

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.
