Description Adam Mariš 2017-04-24 11:10:32 EDT 
Integer overflow in the mark_curve function in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via a crafted PostScript document.

Comment 1 Adam Mariš 2017-04-24 11:11:11 EDT 
Created ghostscript tracking bugs for this issue:

Affects: fedora-all [bug 1444945]
Comment 5 Stefan Cornelius 2017-06-27 12:11:54 EDT 
I can't reproduce this issue. It looks like this bug was introduced when adding a new scanner via http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=18ef67078eb63103ed5e0de627296cb86f493d42

The ghostscript versions we ship do not include this new scanner, thus should be unaffected by it.
Comment 6 Stefan Cornelius 2017-06-27 12:12:06 EDT 
Statement:

This issue did not affect the versions of ghostscript as shipped with Red Hat Enterprise Linux 5, 6, and 7. This issue did not affect the versions of ghostscript as shipped with OpenShift Enterprise 2.
