Bug ID: 1688
Summary: overlength error message in expand.c
Product: Exim
Version: 4.84
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: String expansion
Assignee: nigel@???
Reporter: jasen@???
CC: exim-dev@???
2015-09-04 17:11:45 1ZXuWe-0003TD-9V string_sprintf expansion was longer than
32768 (lookup of "%s" gave DEFER: %s)
this seems to be coming from expand.c
expand_string_message =
string_sprintf("lookup of \"%s\" gave DEFER: %s",
string_printing2(key, FALSE), search_error_message);
goto EXPAND_FAILED;
perhaps the format string should be changed to something like:
"lookup of \"%.20000s\" gave DEFER: %.10000s",
which will result in an under-length string for any inputs.
But I have not found out how to provoke this error. The message-id is unknown
in the main log file. so its probably some ACL code.
If I have an infinite loop causing this error that change would possibly make
matters worse.
