:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that nspluginviewer should be allowed execute access on the nswrapper_32_64.libflashplayer.so file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep nspluginviewer /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 3 Daniel Walsh 2012-09-17 23:07:01 UTC
Did flash seem to work?  Also why are you using a 32 flash plugin when the 64 bit plugin is available.

Comment 4 long 2012-09-18 16:49:55 UTC
No, flash does not work in konqueror when this happens.  I have no idea why it is trying to use the 32-bit plugin.  I have both 32-bit and 64-bit versions installed.

Comment 5 Daniel Walsh 2012-09-20 01:28:08 UTC
I am hesitant to allow it to execute the same location that it writes.

You can turn off the protection of mozilla plugins by executing

setsebool -P 
unconfined_mozilla_plugin_transition 0

Comment 6 long 2012-09-20 14:04:48 UTC
If nspluginviewer isn't supposed to be "executing" its files isn't that a bug in the nspluginwrapper package?

Comment 7 Martin Stransky 2012-09-20 14:10:06 UTC
No, it's not a bug in nspluginwrapper package. It's a bug in flash-plugin. If you believe flash plugin should perform such action (I highly doubt so), follow comment 5.
