If a local attacker can predict this filename, and precreates a

It is fixed in upstream version 4.0.33.
Use CVE-2014-1831 for the vulnerability with the "before 4.0.33"
Use CVE-2014-1832 for the vulnerability with the "4.0.33 and earlier"
Note that while the original CVE request mentions version 4.0.33, that
seems like a typo as upstream NEWS file indicates: Fixed versions:
4.0.37. Consequently, the above should be "before 4.0.37" and "4.0.37
and earlier" (or "before 4.0.38").
