CVE-2010-2055

Ghostscript v8.71 y versiones anteriores, lee los ficheros de inicialización desde el directorio de trabajo actual, lo que permite a usuarios locales ejecutar comandos PostScript de su elección a través de un archivo "Trojan horse" (Caballo de Troya"), relacionado con el soporte inapropiado para la opción -P del programa.

Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures and an interpreter for Portable Document Format files. An integer overflow flaw was found in Ghostscript's TrueType bytecode interpreter. An attacker could create a specially-crafted PostScript or PDF file that, when interpreted, could cause Ghostscript to crash or, potentially, execute arbitrary code. It was found that Ghostscript always tried to read Ghostscript system initialization files from the current working directory before checking other directories, even if a search path that did not contain the current working directory was specified with the "-I" option, or the "-P-" option was used. If a user ran Ghostscript in an attacker-controlled directory containing a system initialization file, it could cause Ghostscript to execute arbitrary PostScript code.
