[Message part 1 (text/plain, inline)]
I'm currently testing the patch for CVE-2017-1000369 in Exim:

https://git.exim.org/exim.git/commit/65e061b76867a9ea7aeeb535341b790b90ae6c21

"To reach the start of the stack with the end of the heap (man brk), we
permanently leak memory through multiple -p command-line arguments that
are malloc()ated by Exim but never free()d (CVE-2017-1000369) -- we call
such a malloc()ated chunk of heap memory a "memleak-chunk"."
