Read the Kernel Rebuild Guide if this is your first time compiling your own kernel Get a 2.6.x kernel from and unpack it to /usr/src Get 26_kernel_ia32-and-x86_ patch -p1 -d /usr/src/linux-2.6.7-rc2 <26_kernel_ia32-and-x86_ Follow the usual steps. Older versions of the 2.6.x should be patched: Patch for 2.6.xx Kernels, x86 and x86_64 The patches should apply cleanly to all 2.4.xx versions. make dep bzImage modules modules_install mount /boot (some distributions mount /boot on startup) cp arch/i386/boot/bzImage /boot Apply the patch patch -p1 -d /usr/src/linux-2.4.26 <24_kernel_ia32-and-x86_ Configure and compile as usual. Unpack the kernel source and make a symbolic link: cd /usr/src/ tar xfvj linux-2.4.26.tar.bz2 ln -s linux-2.4.26 linux 4. Download the latest kernel source, linux-2.4.26.tar.bz2, from your local Linux Kernel Mirror 3. Read the Kernel Rebuild Guide if this is your first time compiling your own kernel 2. X86-64 is missing in Bitkeeper, Andr Tomt posted patches including x86_64 at Ģ4_kernel_ia32-and-x86_64-fix-fpu-state.patchĮvil can not do any damage once this patch is applied, but it will keep running at 99% CPU until it is killed (like any other process).įollow these steps to get a safe vanilla kernel:ġ. Bitkeeper i387.h patch x86 (link removed disabled since it no longer works).
Patch for 2.4.2x Kernels, x86 and x86_64 The right fixes are now declared by the all and mighty hero Linus Torvalds. Luckily, the kernel team were quick to release official patches. Temporary fixes have been posted here (the signal.c patch by Stian Skjelstad and a how-to on installing 2.4.26-rc3-gentoo, a kernel version I discovered was safe before patches became available), but none of these solutions were incredibly great. I hoped some kernels would be unaffected because 2.4.26-rc3-gentoo and 2.4.26_pre6-gentoo are, but sadly almost all kernels versions die when evil is executed. Compiling a large number of different kernel versions just to find that gcc crash.c -o evil &. The last days were frustrating, I wanted to publish a fix together with the exploit code. Alt-SysRq-U (remount all mounted file systems).Alt-SysRq-S (save unsaved data to disk).Magic SysRq key) in your kernel you can cleanly reboot if evil freezes your system with the following keyboard combination: * by Added some stuff by and fixed the fsave line with (*fpubuf). Running this simple C program crashes the Linux kernel. He reported it to the Linux-kernel mailing list and the gcc bugzilla. He was quite surprised when he discovered that the code he was trying froze his machine. The flaw was by accident discovered by Stian Skjelstad when he was doing some code tests while on vacation. If the kernels stops doing it's job, everything else will too.
It handles communication with the computers hardware and decides the priority of running programs (processes).
The kernel is the most important part of the Linux operating system. The security hole affects both 2.4.2x and 2.6.x kernels on the x86 and x86_64 architectures. A Linux kernel bug allows a simple C program crash the kernel, effectively locking the whole system.
