Bug 613965

Summary:

SELinux is preventing /opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010 from
loading /opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6 which requires text relocation.

Detailed Description:

The 5245414C2053747564696F20323031 application attempted to load
/opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6 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/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6 to use relocation as a workaround, until the
library is fixed. Please file a bug report.

Allowing Access:

If you trust /opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6 to run correctly, you can change the file
context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6'" 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/REALSoftware/REALStudio2010r2.1/REAL.Studio.2010.Libs/libRBTypeLibraryReader.so.6'"

Fix Command:

chcon -t textrel_shlib_t '/opt/REALSoftware/REALStudio2010r2.1/REAL Studio 2010
Libs/libRBTypeLibraryReader.so.6'
