Descriptions
An issue was discovered in Artifex Ghostscript before 9.24. Incorrect "restoration of privilege" checking during handling of /invalidaccess exceptions could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction.
Se ha descubierto un problema en versiones anteriores a la 9.24 de Artifex Ghostscript. La comprobación incorrecta de "restoration of privilege" durante el manejo de excepciones /invalidaccess podría ser empleada por atacantes que sean capaces de proporcionar PostScript manipulado para ejecutar código mediante la instrucción "pipe".
It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document.
