Bug 638900

Summary:

SELinux is preventing /opt/google/talkplugin/GoogleTalkPlugin from executing
/opt/google/talkplugin/GoogleTalkPlugin.

Detailed Description:

[GoogleTalkPlugi has a permissive type (mozilla_plugin_t). This access was not
denied.]

SELinux has denied the GoogleTalkPlugi from executing
/opt/google/talkplugin/GoogleTalkPlugin. If GoogleTalkPlugi is supposed to be
able to execute /opt/google/talkplugin/GoogleTalkPlugin, 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 GoogleTalkPlugi is not supposed to execute
/opt/google/talkplugin/GoogleTalkPlugin, this could signal an intrusion attempt.

Allowing Access:

If you want to allow GoogleTalkPlugi to execute
/opt/google/talkplugin/GoogleTalkPlugin: chcon -t bin_t
'/opt/google/talkplugin/GoogleTalkPlugin' If this fix works, please update the
file context on disk, with the following command: semanage fcontext -a -t bin_t
'/opt/google/talkplugin/GoogleTalkPlugin' Please specify the full path to the
executable, Please file a bug report to make sure this becomes the default
labeling.
