Descriptions

The gx_ttfReader__Read function in base/gxttfb.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.

La función gx_ttfReader__Read en option.cc en base/gxttfb.c en Artifex Ghostscript GhostXPS 9.21 permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en memoria dinámica o heap y cierre inesperado de la aplicación) o, probablemente, causar cualquier otro tipo de impacto mediante un archivo modificado.

Kamil Frankowicz discovered that Ghostscript mishandles references. A remote attacker could use this to cause a denial of service. Kim Gwan Yeong discovered that Ghostscript could allow a heap-based buffer over-read and application crash. A remote attacker could use a crafted document to cause a denial of service. Various other issues were also addressed.
