SECURITY: Fix safeguard against upward traversal in msglog files.
Credits: Qualys
3/ In src/deliver.c:
333 static int
334 open_msglog_file(uschar *filename, int mode, uschar **error)
335 {
336 if (Ustrstr(filename, US"/../"))
337 log_write(0, LOG_MAIN|LOG_PANIC,
338 "Attempt to open msglog file path with upward-traversal: '%s'\n", filename);
Should this be LOG_PANIC_DIE instead of LOG_PANIC? Right now it will log
the /../ attempt but will open the file anyway.
(cherry picked from commit 742c27f02d83792937dcb1719b380d3dde6228bf)
(cherry picked from commit 1e9a340c05d7233969637095a8a6378b14de2976)
