CVE-2010-3848

Status Candidate

Overview

Stack-based buffer overflow in the econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2, when an econet address is configured, allows local users to gain privileges by providing a large number of iovec structures.

Linux Kernel Econet Privilege Escalation
Posted Sep 6, 2011
Authored by Jon Oberheide

This exploit leverages three vulnerabilities to escalate privileges. The primary vulnerability is a kernel stack overflow, not a stack buffer overflow as the CVE description incorrectly states. This may be the first public exploit for a kernel stack overflow, and it turns out to be a bit tricky due to some particulars of the econet vulnerability. It involves the econet_sendmsg function, ec_dev_ioctl function, and the ipc subsystem. Linux kernel versions prior to 2.6.36.2 are affected.

Mandriva Linux Security Advisory 2010-257
Posted Dec 17, 2010
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2010-257 - The setup_arg_pages function in fs/exec.c in the Linux kernel before 2.6.36, when CONFIG_STACK_GROWSDOWN is used, does not properly restrict the stack memory consumption of the environment for a 32-bit application on a 64-bit platform, which allows local users to cause a denial of service via a crafted exec system call, a related issue to CVE-2010-2240. drivers/media/video/v4l2-compat-ioctl32.c in the Video4Linux implementation in the Linux kernel before 2.6.36 on 64-bit platforms does not validate the destination of a memory copy operation, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via a VIDIOCSTUNER ioctl call on a /dev/video device, followed by a VIDIOCSMICROCODE ioctl call on this device. Various other issues have been addressed as well.

Ubuntu Security Notice 1023-1 - Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces.
