Descriptions

An issue was discovered in the function gdev_prn_open_printer_seekable() in Artifex Ghostscript through 10.02.0 allows remote attackers to crash the application via a dangling pointer.

Se descubrió un problema en la función gdev_prn_open_printer_seekable() en Artifex Ghostscript hasta la versión 10.02.0 que permite a atacantes remotos bloquear la aplicación mediante un puntero colgante.

A flaw was found in Ghostscript. A remote attacker may use a specially crafted payload to trigger access to previously freed memory, which can potentially lead to remote code execution or an application crash.

It was discovered that Ghostscript, the GPL PostScript/PDF interpreter, does not properly handle errors in the gdev_prn_open_printer_seekable() function, which could result in the execution of arbitrary commands if malformed document files are processed.
