Output of `ps -efZ`

Hi,

I just had a similar SELinux alert preventing abrt-hook-cpp from accessing sigchld (many times in a row. I had the alert already 11 times in like 15 min).
The only diference is that Jared Smith's alert seem to originate from the network manager, and mine from the Mozilla flash plugin (v. 11.2.202.491 updated yesterday from Adobe website).

Below the alert details:

----------------------------------------------------------
SELinux is preventing abrt-hook-ccpp from using the sigchld access on a process.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If you believe that abrt-hook-ccpp should be allowed sigchld access on processes labeled kernel_t 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 abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Attached is the output of `ps -efZ` which you were asking to the reporter (and where I saw that the mozilla_plugin refered in the alert is likely Flash, though PID are different, but it may just have respawned a different process).

Should these accesses be granted or is there a potential issue with Flash?
