Descriptions

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.

La función gs_alloc_ref_array en psi/ialloc.c en Artifex Ghostscript versión 9.21 permite a los atacantes remotos causar una denegación de servicio (DoS) (desbordamiento de búfer en la región heap de la memoria y bloqueo de la aplicación) o posiblemente tener otro impacto no especificado por medio de un documento PostScript creado. Esto está relacionado con la falta de una comprobación de desbordamiento de enteros en base/gsalloc.c.
