se-linux denies access ./plugins from realplay.bin
Denied both "search" and "read"

How reproducible: Always


Steps to Reproduce:
1. Install realplayer
2. Reopen firefox, browse to some streaming media (I chose BBC Iplayer)
3. Observe denials
(Note, there was a denial previous to these that prevented embedded player starting, this was fixed by: chcon -t bin_t '/usr/bin/realplay'
  
Actual results:
No media stream :-(

Expected results:
Media stream

Additional info:
SELinux is preventing realplay.bin (nsplugin_t) "search" to ./plugins (textrel_shlib_t). Detailed DescriptionSELinux denied access requested by realplay.bin. It is not expected that this access is required by realplay.bin and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing AccessSometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for ./plugins, restorecon -v './plugins' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.

Comment 1 Daniel Walsh 2008-12-15 16:24:24 UTC
Why is /opt/real/RealPlayer labeled as textrel_shlib_t?

Does restorecon -R -v /opt/real

Change anything?
