CVE-2008-1940 - Pulverisable Magellanic Penguin

Description

The RBAC functionality in grsecurity before 2.1.11-2.6.24.5 and 2.1.11-2.4.36.2 does not enforce user_transition_deny and user_transition_allow rules for the (1) sys_setfsuid and (2) sys_setfsgid calls which allows local users to bypass restrictions for those calls.
