Taint mismatch, Ustrncpy: retry_update 826 ?

All,

I thought that I had fixed my system's issues with tainted data some
months ago but I appear to be logging one of these in paniclog for each
message processed:

2021-01-25 10:48:56 1l2yKc-0003H9-4x Taint mismatch, Ustrncpy:
retry_update 826

2021-01-25 10:58:56 1l2yKc-0003H9-4x Taint mismatch, Ustrncpy:
retry_update 826

2021-01-25 11:13:56 1l2yKc-0003H9-4x Taint mismatch, Ustrncpy:
retry_update 826

2021-01-25 11:28:57 1l2yKc-0003H9-4x Taint mismatch, Ustrncpy:
retry_update 826

Can someone give me a clue as to where to look?

Mike

You didn't say what version Exim you have, but that
looks possibly like Bug 2492, fixed in 4.94

On closer inspection, I think I am generating one per message stuck on
the queue - each time Exim runs the queue - hence this may relate to
'retry_update'?

Exim 4.93 built from source, 64-bit Devuan 3.0 Beowulf (similar to
Debian 10 but without systemd).

Hello,

Avoid anything greater than 4.92 and earlier than head of
exim-4.94+fixes branch.

FWIW I think a 4.94.1 release would not be a terribly bad idea just for
the documentation updates.
