Description Jacob Isreal 2009-11-19 08:34:14 UTC

SELinux is preventing /home/lonnie/Programs/Songbird/songbird-bin from loading
/home/lonnie/Programs/Songbird/components/sbMediacoreManager.so which requires
text relocation.

Detailed Description:

The songbird-bin application attempted to load
/home/lonnie/Programs/Songbird/components/sbMediacoreManager.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
/home/lonnie/Programs/Songbird/components/sbMediacoreManager.so to use
relocation as a workaround, until the library is fixed. Please file a bug

Allowing Access:

If you trust /home/lonnie/Programs/Songbird/components/sbMediacoreManager.so to
run correctly, you can change the file context to textrel_shlib_t. "chcon -t
'/home/lonnie/Programs/Songbird/components/sbMediacoreManager.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

Fix Command:

chcon -t textrel_shlib_t
