NVD Description
Note: Versions mentioned in the description apply only to the upstream ghostscript-doc package and not the ghostscript-doc package as distributed by Centos.
See How to fix? for Centos: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.
