[rsbac] Urgent Security Bugfix 1.2.3-14

[Andrea Pasquinucci]

Do I understand correctly that there is no bug for v1.2.3 on 2.6 kernel? 
Otherwise which patch should I use? Thanks

Andrea

*     * What is wrong: The syscall sys_sysctl is not intercepted, but 
* the proc interface at /proc/sys/ is intercepted correctly.
*     * Implications: Encapsulated daemons running as root or with 
* additional Linux capabilities can change important system settings. 
* E.g. kernel.modprobe controls, which binary is run by the kernel with 
* root rights when trying to access a not existing device.
*     * Credits: Thanks to Brad Sprengler for hinting at sys_sysctl.
*     * RSBAC versions affected: All versions up to 1.2.4.
*     * What you should do: Apply this patch (MD5 / GnuPG Cert) to get 
* the bug corrected, recompile the kernel, reinstall and reboot.
