Description Casey Dahlin 2013-07-24 11:17:41 EDT
Description of problem:
I'm not certain when this happened. It's backdated.

Given the relationship of the labels, I suspect the access was legitimate, but maybe this is something that should be fixed in firefox and not SELinux policy?
SELinux is preventing /usr/lib64/firefox/firefox (deleted) from using the 'ptrace' accesses on a process.

*****  Plugin catchall (100. 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.
allow this access for now by executing:
# grep firefox /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-07-24 17:36:07 EDT
Looks like firefox is trying to ptrace one  of its plugins, we should allow it unless the user turns on deny_ptrace.

671df206c6c85a6a222809e5bf7b5ab8242a2d80 fixes this in git.
