Test ID:1.3.6.1.4.1.25623.1.0.50496
Category:Ubuntu Local Security Checks
Title:Ubuntu 4.10 USN-60-0 (linux-source-2.6.8.1)
Summary:Ubuntu 4.10 USN-60-0 (linux-source-2.6.8.1)
Description:
The remote host is missing an update to linux-source-2.6.8.1
announced via advisory USN-60-0.

CVE-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 CVE-2004-0883,
CVE-2004-0949). However, it was found that these new validation checks
were too strict, which cause some valid operations to fail.

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

Solution:
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.
