"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
