Bug 543855

Summary:

SELinux is preventing googleearth-bin from loading
/opt/google-earth/libminizip.so which requires text relocation.

Detailed Description:

The googleearth-bin application attempted to load
/opt/google-earth/libminizip.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
/opt/google-earth/libminizip.so to use relocation as a workaround, until the
library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Allowing Access:

If you trust /opt/google-earth/libminizip.so to run correctly, you can change
the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/google-earth/libminizip.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 '/opt/google-earth/libminizip.so'"

Fix Command:

chcon -t textrel_shlib_t '/opt/google-earth/libminizip.so'
