>SELinux is preventing /usr/lib64/firefox/firefox (deleted) from using the ptrace access on a process.
>
>*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
>
>If you want to allow sysadm to debug or ptrace all processes.
>Then you must tell SELinux about this by enabling the 'deny_ptrace' boolean.You can read 'mozilla_selinux' man page for more details.
>Do
>setsebool -P deny_ptrace 0
>
>*****  Plugin catchall (11.6 confidence) suggests  ***************************
>
>If you believe that firefox (deleted) should be allowed ptrace access on processes labeled mozilla_plugin_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 firefox /var/log/audit/audit.log | audit2allow -M mypol
># semodule -i mypol.pp
