Description Laurent Rineau 2010-08-18 16:08:18 UTC
Summary:

SELinux is preventing /bin/bash from executing
/etc/kde/shutdown/gpg-agent-shutdown.sh.

Detailed Description:

SELinux has denied the startkde from executing
/etc/kde/shutdown/gpg-agent-shutdown.sh. If startkde is supposed to be able to
execute /etc/kde/shutdown/gpg-agent-shutdown.sh, this could be a labeling
problem. Most confined domains are allowed to execute files labeled bin_t. So
you could change the labeling on this file to bin_t and retry the application.
If this startkde is not supposed to execute
/etc/kde/shutdown/gpg-agent-shutdown.sh, this could signal an intrusion attempt.

Allowing Access:

If you want to allow startkde to execute
/etc/kde/shutdown/gpg-agent-shutdown.sh: chcon -t bin_t
'/etc/kde/shutdown/gpg-agent-shutdown.sh' If this fix works, please update the
file context on disk, with the following command: semanage fcontext -a -t bin_t
'/etc/kde/shutdown/gpg-agent-shutdown.sh' Please specify the full path to the
executable, Please file a bug report to make sure this becomes the default
labeling.
