The original code didn't account for the fact that strchr() would match on the '\0' character, making it read past the end of the buffer if no non-whitespace character was present. This bug was introduced in commit ec5ff44 which was first released in systemd v221 and later fixed in commit 8595102 which was released in v240, so versions in the range [v221, v240) are affected.
The test cases from commit 8595102 check for the return value of syslog_parse_identifier() and will catch the condition that produced vulnerability from CVE-2018-16866. Add these tests to our stable branches. Tested that these tests will fail if the fix for CVE-2018-16866 is missing from the branch.

This function returns 0 on success and a negative value on failure. On success,
it writes the parsed action to the address passed in its third argument.
`bus_set_transient_emergency_action` does this:
r = parse_emergency_action(s, system, &v);
if (v < 0)
// handle failure
However, `v` is not updated if the function fails, and this should be checking
`r` instead of `v`.
The result of this is that if an invalid failure (or success) action is
specified, systemd ends up creating the unit anyway and then misbehaves if it
tries to run the failure action because the action value comes from
uninitialized stack data. In my case, this resulted in a failed assertion:
Program received signal SIGABRT, Aborted.
