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 The problem can be corrected by upgrading the affected package to version 2.6.8.1-16.12. You need to reboot the computer after doing a standard system upgrade to effect the necessary changes. Details follow: A remote Denial of Service vulnerability was discovered in the Netfilter IP packet handler. This allowed a remote attacker to crash the machine by sending specially crafted IP packet fragments. (CAN-2005-0209) The Netfilter code also contained a memory leak. Certain locally generated packet fragments are reassembled twice, which caused a double allocation of a data structure. This could be locally exploited to crash the machine due to kernel memory exhaustion. (CAN-2005-0210) Ben Martel and Stephen Blackheath found a remote Denial of Service vulnerability in the PPP driver. This allowed a malicious pppd client to crash the server machine. (CAN-2005-0384) Georgi Guninski discovered a buffer overflow in the ATM driver. The atm_get_addr() function does not validate its arguments sufficiently, which could allow a local attacker to overwrite large portions of kernel memory by supplying a negative length argument. This could eventually lead to arbitrary code execution. (CAN-2005-0531) Georgi Guninski also discovered three other integer comparison problems in the TTY layer, in the /proc interface and the ReiserFS driver. However, the previous Ubuntu security update (kernel version 2.6.8.1-16.11) already contained a patch which checks the arguments to these functions at a higher level and thus prevents these flaws from being exploited. (CAN-2005-0529, CAN-2005-0530, CAN-2005-0532) Georgi Guninski discovered an integer overflow in the sys_epoll_wait() function which allowed local users to overwrite the first few kB of physical memory. However, very few applications actually use this space (dosemu is a notable exception), but potentially this could lead to privilege escalation. (CAN-2005-0736) Eric Anholt discovered a race condition in the Radeon DRI driver. In some cases this allowed a local user with DRI privileges on a Radeon card to execute arbitrary code with root privileges. Finally this update fixes a regression in the NFS server driver which was introduced in the previous security update (kernel version 2.6.8.1-16.11). We apologize for the inconvenience.

14965 | Linux Kernel Netfliter IP Packet Fragment DoS |
14871 | Linux Kernel reiserfs_copy_from_user_to_file_region Function Local Overflow A local overflow exists in Linux Kernel. The Linux Kernel code performs poor input validation in the reiserfs_copy_from_user_to_file_region function when used with 64 bit architectures due to discrepancies between the size_t and the int data type resulting in a local buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity. |
14810 | Linux Kernel Malformed PPP Packet Remote DoS Kernel contains a flaw in drivers/net/ppp_async.c that may allow a remote denial of service. The issue is triggered when a remote user sends a specially crafted PPP packet, and will result in loss of availability for the platform. No further details have been provided. |
