Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-3335-2)

High Nessus Plugin ID 100987

Synopsis

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

Description

USN-3335-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 ESM.

It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges.

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. Note that the updated package may not be immediately available from the package repository and its mirrors.
