A race condition vulnerability was discovered in NetworkManager. Temporary files were created insecurely when saving or updating connection settings, which could allow local users to read connection secrets such as VPN passwords or WiFi keys.
A race condition that could disclose connection secrets to authenticated local users when changing ifcfg and keyfile connections was found.
Created NetworkManager tracking bugs for this issue:
Affects: fedora-all [bug 1324027]
Fix from upstream: https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=60b7ed3bdc3941a3b7c56824fba4b7291e79041f
rhel-5 version 0.7.0 unaffected: the vulnerable behaviour was introduced between 0.7.1 and 0.7.2.
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.
