That only solves one of the two exploit methods. modutils 2.3.20 solves both without any kernel changes, mainly so it fixes the problem on all kernels, including 2.2. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
