CVE-2017-9835 (opens in a new tab)How to fix?
There is no fixed version for RHEL:7 libgs.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgs package and not the libgs package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c.
