Summary:

SELinux is preventing /opt/teamviewer/teamviewer/5/wine/bin/wine-preloader from
loading /opt/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.so which requires
text relocation.

Detailed Description:

The wineboot.exe application attempted to load
/opt/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.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/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.so to use relocation as a
workaround, until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /opt/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.so to run
correctly, you can change the file context to textrel_shlib_t. "chcon -t
textrel_shlib_t '/opt/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.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/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.so'"

Fix Command:

chcon -t textrel_shlib_t '/opt/teamviewer/teamviewer/5/wine/lib/wine/mpr.dll.so'
