Yes it is fixed in kernel-source 2.4.18-13. However, due to another issue introduced by the security fix, you should download the latest kernels from http://auric.debian.org/~herbert/. Thanks for your answer. 2.4.18-12 works without segfaults. Is something wrong in 2.4.18-12 more? Is that local or remote exploitable issues? When 2.4.18-13 will be in stable tree of debian?
