This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Symlink Attack. Shibboleth Service Provider (SP) 3.x before 3.1.0 shipped a spec file that calls chown on files in a directory controlled by the service user (the shibd account) after installation. This allows the user to escalate to root by pointing symlinks to files such as /etc/shadow.
