CVE-2016-4477 [HIGH] CVE-2016-4477 wpa_supplicant: local configuration update allows privilege escalation
CVE-2016-4477 wpa_supplicant: local configuration update allows privilege escalation
The local configuration update through the control interface SET_NETWORK
command could allow privilege escalation for the local user to run code
from a locally stored library file under the same privileges as the
wpa_supplicant process has. The assumption here is that a not fully
trusted user/application might have access through a connection manager
to set network profile parameters like psk, but would not have access to
set other configuration file parameters. If the connection manager in
such a case does not filter out control characters from the psk value,
it could have been possible to practically update the global parameters
by embedding a newline character within the psk value. In addition, the
