Ubuntu 14.04 LTS : Linux kernel vulnerability (USN-2274-1)

high Nessus Plugin ID 76386

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2274-1 advisory.

 - The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. (CVE-2014-4699)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
