CVE-2002-0909

Estado: ModificadaAlta (7.5)—

Múltiples desbordamientos de búfer en mnews 1.22 y anteriores permiten: a un servidor NNTP remoto ejecutar código arbitrario mediante respuestas largas, o a usuarios locales ganar privilegios mediante argumentos de línea de comando largos (-f, -n, -D, -M, -p), o mediante variables de entorno largas (JNAMES, MAILSERVER).
