Descriptions

An issue was discovered in Artifex Ghostscript before 9.24. A type confusion in "ztype" could be used by remote attackers able to supply crafted PostScript 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. Una confusión de tipos en "ztype" podría ser empleada por atacantes remotos que puedan proporcionar PostScript manipulado para provocar el cierre inesperado del intérprete o, posiblemente, otro tipo de impacto sin especificar.

It was discovered that the ghostscript .type operator did not properly validate its operands. A specially crafted PostScript document could exploit this to crash ghostscript or, possibly, execute arbitrary code in the context of the ghostscript process.
