Descriptions
In Artifex Ghostscript 9.23 before 2018-08-24, attackers able to supply crafted PostScript could use uninitialized memory access in the aesdecode operator to crash the interpreter or potentially execute code.
En Artifex Ghostscript 9.23 antes del 24/08/2018, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear un acceso a la memoria no inicializada en el operador aesdecode para provocar el cierre inesperado del intérprete o ejecutar código.
It was discovered that ghostscript did not properly verify the key used in aesdecode. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document.
Tavis Ormandy discovered multiple vulnerabilities in Ghostscript, an interpreter for the PostScript language, which could result in denial of service, the creation of files or the execution of arbitrary code if a malformed Postscript file is processed (despite the dSAFER sandbox being enabled).
