[VIM] Exim - 2003, possible dupes?

Buffer overflow in Exim before 4.21 allows remote attackers to cause a 
denial of service via an SMTP EHLO/HELO command with a large number of 
spaces followed by a NULL character and CRLF, which is not properly 
trimmed before the "(no argument given)" string is appended to the buffer.

Heap-based buffer overflow in smtp_in.c for Exim 3 (exim3) before 3.36 and 
Exim 4 (exim4) before 4.21 may allow remote attackers to execute arbitrary 
code via an invalid (1) HELO or (2) EHLO argument with a large number of 
spaces followed by a NULL character and a newline.


1. dates are very close
2. SMTP
3. HELO/EHLO commands
4. "large number of spaces followed by a NULL char and a newline"

Based on those four points, this seems like a possible duplicate issue. 
Thoughts?
