SELinux is preventing the realplay.bin from using potentially mislabeled files (./realplayerrc)
Description of problem:
When using RealPlayer 11 and nspluginwrapper, SELINUX throws two AVCs (attached) when playing Real audio content.
Version-Release number of selected component (if applicable)
Steps to Reproduce:
1. Install RealPlayer
2. Install nspluginwrapper
3. Enable allow_unconfined_nsplugin_transition in selinux policy
4. Browse to, e.g. http://www.bbc.co.uk/radio3/ and attempt to play an audio stream.
5. Two AVC denials result:
SELinux is preventing the realplay.bin from using potentially mislabeled files
SELinux is preventing realplay.bin (nsplugin_t) "execute" to ./realplay.bin
Full AVC alerts are attached.

Three AVCs for RealPlayer relating to binding & port access
RealPlayer also seems to throw AVCs when trying to bind to ports -- the following three AVCs:
1) SELinux is preventing realplay.bin (nsplugin_t) "node_bind" inaddr_any_node_t
2) SELinux is preventing the realplay.bin (nsplugin_t) from binding to port 6970.
3) SELinux is preventing the realplay (nsplugin_t) from executing ./realpla
Ok I Fixed most in selinux-policy-3.5.13-27.fc10
I don't want to allow realplayer to bind to that port though.
You can disable nsplugin confinement if you want full realplayer
setsebool -P allow_unconfined_nsplugin_transition = 0
RealPlayer allows a user to bind to a specific, defined port for UDP -- the default is 7070. Does it make sense to allow it to bind to this particular port?
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. 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bug reports from releases that are no longer maintained.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 '10'.
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 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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.
The process we are following is described here:
Closing as closed in the current release.
