[exim-dev] [Bug 2541] New: segfault on invalid -f flag

https://bugs.exim.org/show_bug.cgi?id=2541

            Bug ID: 2541
           Summary: segfault on invalid -f flag
           Product: Exim
           Version: 4.93
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: General execution
          Assignee: unallocated@???
          Reporter: john@???
                CC: exim-dev@???

The taint functionality added to the CLI "-f" flag in version 4.93 will end up
calling

sender_address = string_copy_taint(sender_address, TRUE);

when sender_address is a null pointer. This segfaults when
string_copy_taint_trc() tries to determine the length of the string.

To reproduce the crash run:

    exim -f @ -bV
