Description Paolo Niccolò Giubelli 2009-11-20 12:31:17 UTC
Summary:

SELinux is preventing swriter.bin from loading
/opt/jre1.6.0_16/lib/i386/client/libjvm.so which requires text relocation.

Detailed Description:

The swriter.bin application attempted to load
/opt/jre1.6.0_16/lib/i386/client/libjvm.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/jre1.6.0_16/lib/i386/client/libjvm.so 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 /opt/jre1.6.0_16/lib/i386/client/libjvm.so to run correctly, you
can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/jre1.6.0_16/lib/i386/client/libjvm.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/jre1.6.0_16/lib/i386/client/libjvm.so'"

Fix Command:

chcon -t textrel_shlib_t '/opt/jre1.6.0_16/lib/i386/client/libjvm.so'
