Descriptions

ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.

ProFTPD versiones anteriores a 1.3.6b y versiones 1.3.7rc anteriores a 1.3.7rc2, permite una denegación de servicio remota no autenticada debido al manejo incorrecto de comandos demasiado largos porque el archivo main.c en un proceso secundario entra en un bucle infinito.
