proc and Exim debug info

There is a heap overflow in string_vformat().Using a EHLO message, remote code execution seems to be possible.
Comment 1 Jeremy Harris 2019-09-27 11:01:35 UTC
Seemingly fixed by f3ebb786e4 in mainline, though that's fairly unhelpful as it
is a massive feature-patch
Comment 2 Jeremy Harris 2019-09-27 12:32:04 UTC
It's a simple coding error, not growing a string by enough.  One-line fix.
The code section was rewritten in the above commit, hence the fix there.
Comment 3 Jeremy Harris 2019-09-27 12:35:36 UTC
Affected releases: 4.92 4.92.1 4.92.2  (4.91 not affected by this).
