Descriptions

The open_envvar function in xdg-open in xdg-utils before 1.1.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL, as demonstrated by %s in this environment variable.

La función open_envvar en xdg-open en xdg-utils en versiones anteriores a la 1.1.3 no valida cadenas antes de iniciar el programa especificado por la variable de entorno BROWSER. Esto permite que atacantes remotos lleven a cabo ataques de inyección de argumentos mediante una URL manipulada, tal y como demuestra %s en esta variable de entorno.
