Bug 552708

Summary:

SELinux is preventing /usr/bin/totem from loading
/usr/local/lib/codecs/drv3.so.6.0 which requires text relocation.

Detailed Description:

The totem application attempted to load /usr/local/lib/codecs/drv3.so.6.0 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/local/lib/codecs/drv3.so.6.0 to use relocation as a workaround, until the
library is fixed. Please file a bug report.

Allowing Access:

If you trust /usr/local/lib/codecs/drv3.so.6.0 to run correctly, you can change
the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/local/lib/codecs/drv3.so.6.0'" 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/local/lib/codecs/drv3.so.6.0'"

Fix Command:

chcon -t textrel_shlib_t '/usr/local/lib/codecs/drv3.so.6.0'
