Secunia

Two vulnerabilities have been reported in RSBAC, potentially allowing malicious, local users to escalate their privileges.

1) In certain configurations, it is possible for a malicious, unprivileged user to switch the AUTH module off. The problem is that the FF, RC, and ACL modules fail to prevent the AUTH module from being switched off, if self protection is disabled and module switching is enabled. This only affects the AUTH module.

This vulnerability affects versions 1.0.8 through 1.2.2.

2) The "CREATE" module fails to check the mode values, allowing malicious users to create suid and sgid files. This can be exploited to escalate privileges inside the jail.

This vulnerability affects version 1.2.2.

Solution
Update to version 1.2.3.
