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.
Notes
| Author | Note |
|---|---|
| ebarretto | According to Debian: This is an issue in the upstream provided spec file which is not relevant for the binary packages build in Debian (fixed upstream in 3.1.0). The postinst in the Debian packaging does not have similar problematic chown logic. |
