Detail
| A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: linux-image-2.6.8.1-5-386 linux-image-2.6.8.1-5-686 linux-image-2.6.8.1-5-686-smp linux-image-2.6.8.1-5-amd64-generic linux-image-2.6.8.1-5-amd64-k8 linux-image-2.6.8.1-5-amd64-k8-smp linux-image-2.6.8.1-5-amd64-xeon linux-image-2.6.8.1-5-k7 linux-image-2.6.8.1-5-k7-smp linux-image-2.6.8.1-5-power3 linux-image-2.6.8.1-5-power3-smp linux-image-2.6.8.1-5-power4 linux-image-2.6.8.1-5-power4-smp linux-image-2.6.8.1-5-powerpc linux-image-2.6.8.1-5-powerpc-smp linux-patch-debian-2.6.8.1 linux-source-2.6.8.1 The problem can be corrected by upgrading the affected package to version 2.6.8.1-16.14. You need to reboot the computer after doing a standard system upgrade to effect the necessary changes. Details follow: Alexander Nyberg discovered an integer overflow in the sysfs_write_file() function. A local attacker could exploit this to crash the kernel or possibly even execute arbitrary code with root privileges by writing to an user-writable file in /sys under certain low-memory conditions. However, there are very few cases where a user-writeable sysfs file actually exists. (CAN-2005-0867) Olof Johansson discovered a Denial of Service vulnerability in the futex functions, which provide semaphores for exclusive locking of resources. A local attacker could possibly exploit this to cause a kernel deadlock. (CAN-2005-0937) In addition this update fixes two race conditions in the ext3 and jfs file system drivers, which could lead to a kernel crash under certain (unusual) conditions. However, these cannot easily be triggered by users, thus they are not security sensitive.

| 15488 | Linux Kernel sysfs File Write Overflow A local overflow exists in Linux Kernel. The "sysfs_write_file" function fails to validate the integer. By overwriting kernel memory by writing to a sysfs file, an attacker may cause a denial of service or run arbitrary commands with root privileges. |
