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

Medium Nessus Plugin ID 20679

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.9

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.
