Description ziaro40 2010-01-08 17:57:07 UTC
Summary:

SELinux is preventing /opt/Unify/SQLBase/dblxsrv from loading
/opt/Unify/SQLBase/libgptsblmsui11.so which requires text relocation.

Detailed Description:

The dblxsrv application attempted to load /opt/Unify/SQLBase/libgptsblmsui11.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/Unify/SQLBase/libgptsblmsui11.so to use relocation as a workaround, until
the library is fixed. Please file a bug report.

Allowing Access:

If you trust /opt/Unify/SQLBase/libgptsblmsui11.so to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/Unify/SQLBase/libgptsblmsui11.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/Unify/SQLBase/libgptsblmsui11.so'"

Fix Command:

chcon -t textrel_shlib_t '/opt/Unify/SQLBase/libgptsblmsui11.so'

Comment 1 Daniel Walsh 2010-01-09 13:59:08 UTC
Execute the chcon command in the alert and it should work.

Miroslav, could you add this label.
