Summary:

SELinux is preventing vlc from loading /usr/lib/sse2/libpostproc.so.51.2.0 which
requires text relocation.

Detailed Description:

The vlc application attempted to load /usr/lib/sse2/libpostproc.so.51.2.0 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/sse2/libpostproc.so.51.2.0 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 /usr/lib/sse2/libpostproc.so.51.2.0 to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/sse2/libpostproc.so.51.2.0'" 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/sse2/libpostproc.so.51.2.0'"

Fix Command:

chcon -t textrel_shlib_t '/usr/lib/sse2/libpostproc.so.51.2.0'
