Descriptions

An issue was discovered in Artifex Ghostscript before 9.24. Incorrect exec stack handling in the "CS" and "SC" PDF primitives could be used by remote attackers able to supply crafted PDFs to crash the interpreter or possibly have unspecified other impact.

Se ha descubierto un problema en versiones anteriores a la 9.24 de Artifex Ghostscript. El manejo incorrecto de la pila de ejecución en las primitivas PDF "CS" y "SC" podría ser empleado por atacantes remotos que puedan proporcionar PDF manipulados para provocar el cierre inesperado del intérprete o, posiblemente, otro tipo de impacto sin especificar.

It was discovered that Ghostscript contained multiple security issues. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could possibly use these issues to access arbitrary files, execute arbitrary code, or cause a denial of service.
