>Fix remotely exploitable stack overrun in Milliwatt
>
>Milliwatt is vulnerable to a remotely exploitable stack overrun when using
>the 'o' option.  This occurs due to the milliwatt_generate function not
>accounting for AST_FRIENDLY_OFFSET when calculating the maximum number of
>samples it can put in the output buffer.  For channels using a format with 
>a sample rate less than 32kHz, the buffer overrun should not be possible as
>the buffer allocated is sufficient to hold the data, even with no bounds
>checking.  For formats with a sample rate greater then 32kHz however, the
>fixed length buffer will be overrun.
>
>This patch resolves this issue by taking into account AST_FRIENDLY_OFFSET
>when determining the maximum number of samples allowed.  Note that at no
>point is remote code execution possible.  The data that is written into the
>buffer is the pre-defined Milliwatt data, and not custom data.
