Comment 1 Adam Mariš 2016-04-05 11:34:52 UTC

Created NetworkManager tracking bugs for this issue:

Affects: fedora-all [bug 1324027]

Comment 2 Doran Moppert 2016-05-12 07:10:59 UTC

Fix from upstream:   https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=60b7ed3bdc3941a3b7c56824fba4b7291e79041f

Comment 5 Doran Moppert 2016-05-13 04:27:07 UTC

rhel-5 version 0.7.0 unaffected:  the vulnerable behaviour was introduced between 0.7.1 and 0.7.2.

Comment 7 Doran Moppert 2016-05-20 04:16:03 UTC

From upstream description of the flaw:

> could enable an unprivileged authenticated local user to read connection
> secrets while the connection is being saved.

The opportunity and impact of this vulnerability is very low, so tagging WONTFIX for rhel-6.
