Ubuntu 14.04 LTS / 16.04 LTS : NVIDIA graphics drivers vulnerability (USN-3521-1)

medium Nessus Plugin ID 105723

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Jann Horn discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. A local attacker could use this to expose sensitive information, including kernel memory.

This update provides mitigations to address the issue, along with compatibility fixes for the corresponding Linux kernel updates.

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.
