Bug 1024387

Description of problem:
Some plugin is trying to access someone else's home directory.  Firefox is running as jweiss, but it's trying to getattr in /home/.ecryptfs.  I think it's the google talk plugin doing this, but I'm not sure whose job it is to avoid this kind of access.  I could definitely believe this is google's fault, but thought I'd report it here just in case.



Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Set up your home directory with ecryptfs
2. install google talk plugin
2. Run firefox 
3. load http://plus.google.com or gmail.com

Actual results:


Expected results:


Additional info:
SELinux is preventing /usr/lib64/xulrunner/plugin-container from getattr access on the file /home/.ecryptfs/jweiss/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPO-5VRk7yZ89QHJRGgeH4GU--/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPcu.qfiED.KTJst0Fq02Ep.3Vr7yJ01I5Mdd44yuIlVQ-/ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPW4-NJDEp13KCjDKdqTfDAe3FoLPJzZhdBl5l4Xp.3MU-.

Then you can run restorecon.

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

If you believe that plugin-container should be allowed getattr access on the ECRYPTFS_FNEK_ENCRYPTED.FXbFLa1W0sVYoUTxzijOD4iFMHkEqhdFkAUPW4-NJDEp13KCjDKdqTfDAe3FoLPJzZhdBl5l4Xp.3MU- 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 plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
