Bug 624304

Summary:

SELinux is preventing /usr/share/package-converter/Package-Converter from
loading /home/aaronl/.tmpAppData/XDfibbo_libRBShell.so which requires text
relocation.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

The Package-Convert application attempted to load
/home/aaronl/.tmpAppData/XDfibbo_libRBShell.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
/home/aaronl/.tmpAppData/XDfibbo_libRBShell.so to use relocation as a
workaround, until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /home/aaronl/.tmpAppData/XDfibbo_libRBShell.so to run correctly,
you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/home/aaronl/.tmpAppData/XDfibbo_libRBShell.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
'/home/aaronl/.tmpAppData/XDfibbo_libRBShell.so'"

Fix Command:

chcon -t textrel_shlib_t '/home/aaronl/.tmpAppData/XDfibbo_libRBShell.so'
