Description of problem:
tried vlc playlist from a-1radio.com, in firefox
SELinux is preventing mplayer from 'execmod' accesses on the file /usr/lib/libmpg123.so.0.36.4.

*****  Plugin allow_execmod (91.4 confidence) suggests  **********************

If you want to allow mplayer to have execmod access on the libmpg123.so.0.36.4 file
Then you need to change the label on '/usr/lib/libmpg123.so.0.36.4'
Do
# semanage fcontext -a -t textrel_shlib_t '/usr/lib/libmpg123.so.0.36.4'
# restorecon -v '/usr/lib/libmpg123.so.0.36.4'

*****  Plugin catchall (9.59 confidence) suggests  ***************************

If you believe that mplayer should be allowed execmod access on the libmpg123.so.0.36.4 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 mplayer /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 5 Fedora End Of Life 2013-12-21 15:45:07 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 6 Fedora Update System 2014-01-05 06:07:35 UTC
selinux-policy-3.11.1-108.fc18 has been pushed to the Fedora 18 stable repository.  If problems still persist, please make note of it in this bug report.
