Bug 539810

Summary:

SELinux is preventing /usr/lib/vmware/bin/appLoader from loading
/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so which requires text
relocation.

Detailed Description:

The vmware-gksu application attempted to load
/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so which requires text
relocation. This is a potential security problem. Most libraries do not need
this permission. Libraries are sometimes coded incorrectly and request this
permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so to use relocation as a
workaround, until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so to run
correctly, you can change the file context to textrel_shlib_t. "chcon -t
textrel_shlib_t '/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so'" You
must also change the default file context files on the system in order to
preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t
'/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so'"

Fix Command:

chcon -t textrel_shlib_t
'/usr/lib/vmware/lib/libvmware-gksu.so/libvmware-gksu.so'
