Posted on: 01/14/2005 04:18 PM

A Linux kernel update is available for Ubuntu Linux 4.10

==========================================================
Ubuntu Security Notice USN-60-0 January 14, 2005
linux-source-2.6.8.1 vulnerabilities
CAN-2005-0001
http://lists.netsys.com/pipermail/full-disclosure/2005-January/030660.html
==========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

linux-image-2.6.8.1-4-386
linux-image-2.6.8.1-4-686
linux-image-2.6.8.1-4-686-smp
linux-image-2.6.8.1-4-amd64-generic
linux-image-2.6.8.1-4-amd64-k8
linux-image-2.6.8.1-4-amd64-k8-smp
linux-image-2.6.8.1-4-amd64-xeon
linux-image-2.6.8.1-4-k7
linux-image-2.6.8.1-4-k7-smp
linux-image-2.6.8.1-4-power3
linux-image-2.6.8.1-4-power3-smp
linux-image-2.6.8.1-4-power4
linux-image-2.6.8.1-4-power4-smp
linux-image-2.6.8.1-4-powerpc
linux-image-2.6.8.1-4-powerpc-smp
linux-patch-debian-2.6.8.1

The problem can be corrected by upgrading the affected package to version 2.6.8.1-16.10. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

CAN-2005-0001:

Paul Starzetz discovered a race condition in the Linux page fault handler code. This allowed an unprivileged user to gain root privileges on multiprocessor machines under some circumstances. This also affects the Hyper-Threading mode on Pentium 4 processors.

http://lists.netsys.com/pipermail/full-disclosure/2005-January/030660.html:

Brad Spengler discovered that some device drivers used
copy_from_user() (a function to copy data from userspace tools into
kernel memory) with insufficient input validation. This potentially
allowed users and/or malicious hardware to overwrite kernel memory
which could result in a crash (Denial of Service) or even root
privilege escalation.

Additionally, this update corrects the SMB file system driver.
USN-30-1 fixed some vulnerabilities in this driver (see CAN-2004-0883,
CAN-2004-0949). However, it was found that these new validation checks
were too strict, which cause some valid operations to fail.
