:SELinux is preventing /usr/bin/python2.7 from read, open access on the file /usr/sbin/wpa_cli.
:*****  Plugin leaks (86.2 confidence) suggests  ******************************
:If you want to ignore python2.7 trying to read open access the wpa_cli file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:# grep /usr/bin/python2.7 /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp
:*****  Plugin catchall (14.7 confidence) suggests  ***************************
:If you believe that python2.7 should be allowed read open access on the wpa_cli file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep wicd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Johann Suhm 2012-07-16 20:40:04 EDT
this happens when connecting to a WPA2 wireless network with wicd.

Connecting to an open wireless network works fine.
