specially crafted file."

And.


"The vulnerability is caused due to two off-by-one errors in the
"_xlate_ascii_write()" function. These can be exploited by sending a
specially crafted "RETR" FTP command with a 1023 bytes long argument
starting with a linefeed character."

Different?

I am not expert, and was wondering If this was actually something new in
the same ASCII File translation.?

i really don't think the vuln is new. The advisory you sent says proftpd < 
1.2.9rc3 is vulnerable. 1.2.9rc3 was exactly the version THIS BUG was fixed.
