Hi,

the following vulnerability was published for ghostscript.

CVE-2017-8291[0]:
| Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote
| command execution via a "/OutputFile (%pipe%" substring in a crafted
| .eps document that is an input to the gs program, as exploited in the
| wild in April 2017.

Regading the CVE assignment, note that it is psecific to the shell
injection, as per
https://bugs.ghostscript.com/show_bug.cgi?id=697808#c1 if the
segmentation violation that is seen when executing this sample
represents a second security issue then it will get a second CVE.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
