Ubuntu 4.10 : linux-source-2.6.8.1 vulnerabilities (USN-60-0)

medium Nessus Plugin ID 20679
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

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.

Solution

Update the affected packages.
