Description Vincent Danen 2012-05-23 22:32:47 UTC
It was reported [1] that the default permissions of /etc/hostapd/hostapd.conf were insecure (0644) considering they could contain credentials (PSKs, shared radius secrets, etc.) that would then be world readable.

This is a low-impact flaw that be mitigated by changing the permissions to the file (upstream has done this now).

This was assigned CVE-2012-2389 [2] (although no credentials are written by any tools or by default to this file, so an administrator should logically tighten up the permissions if saving sensitive information to the file).
