Description:
 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.
