Summary:

SELinux is preventing /lib/ld-2.11.1.so from loading
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.so which
requires text relocation.

Detailed Description:

The ld-linux.so.2 application attempted to load
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.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
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.so to use
relocation as a workaround, until the library is fixed. Please file a bug
report.

Allowing Access:

If you trust /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.so
to run correctly, you can change the file context to textrel_shlib_t. "chcon -t
textrel_shlib_t
'/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.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
'/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.so'"

Fix Command:

chcon -t textrel_shlib_t
'/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libnnz10.so'
