CVE-2006-6169

Estado: ModificadaMedia (6.8)—
Desbordamiento de búfer basado en montículo en la función ask_outfile_name en el openfile.c para GnuPG (gpg) 1.4 y 2.0, cuando se está ejecutando interactivamente, podría permitir a atacantes remotos ejecutar código de su elección mediante mensajes con expansiones "C-escape", que provocan que la función make_printable_string devuelva una cadena más larga de lo esperado mientras construye un aviso.
