Summary: SELinux is preventing /usr/lib/nspluginwrapper/npviewer.bin "execmod" access on /usr/lib/firefox/plugins/libractrl.so. Detailed Description: SELinux denied access requested by npviewer.bin. The current boolean settings do not allow this access. If you have not setup npviewer.bin to require this access this may signal an intrusion attempt. If you do intend this access you need to change the booleans on this system to allow the access. Allowing Access: Confined processes can be configured to run requiring different access, SELinux provides booleans to allow you to turn on/off access as needed. The boolean allow_execmod is set incorrectly.

Execute the chcon command suggested. Fixed in selinux-policy-3.6.32-53.fc12.noarch Please report this as a bug to logmein-client. They probably need to fix the way their library is built. http://people.redhat.com/~drepper/selinux-mem.html The above link explains the access check.
