Description :

CVE-2005-0001:

Paul Starzetz discovered a race condition in the Linux page fault
handler code. This permited an unprivileged user to gain root
rights 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
permited 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.

Solution :

Upgrade to :
- linux-doc-2.6.8.1-2.6.8.1-16.10 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-2.6.8.1-16.10 (Ubuntu 4.10)

- linux-headers-2.6.8.1-4-686-2.6.8.1-16.10 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-686-smp-2.6.8.1-16.10 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-generic-2.6.8.1-16.10 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-k8-2.6.8.1-16.10 (Ubuntu 4.10)
