Description:
A security issue has been reported in grsecurity, which can be exploited by malicious, local users to bypass certain security restrictions.
The security issue is caused due to an error in the RBAC system when enforcing the "user_transition_deny" and "user_transition_allow" rules. This can be exploited to bypass the affected rules in calls to "sys_setfsuid()" and "sys_setfsgid()".
The security issue is reported in versions prior to 2.1.11-2.6.24.5 (2008-04-21) and 2.1.11-2.4.36.2 (2008-04-21).
