[bug-inetutils] memory exhaustion in ftpd/ftpd.c

[Eric Schmeddes]

Hello,

I would like report a memory exhaustion problem occurring when
getting a binary file larger than the available memory from a
machine running ftpd using mmap().

The problem occurs in the function send_data() in ftpd/ftpd.c,
when using mmap() to access the file. It seems that when the
current get position in the mmapped buffer exceeds the currently
available machine memory, the running ftpd process gets killed
by the kernel.

I have only be able to reproduce this error when running without
a swap partition.

Regards,
