SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 5477)

This is a respin of the previous kernel update, which got retracted due to an IDE-CDROM regression, where any IDE CDROM access would hang or crash the system. Only this problem was fixed additionally. This kernel update fixes the following security problems : - On x8664 a denial of service attack...
