Ubuntu 14.04 LTS : Linux kernel (Xenial HWE) vulnerabilities (USN-3189-2)

high Nessus Plugin ID 97017

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3189-2 advisory.

 USN-3189-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS.

 Mikulas Patocka discovered that the asynchronous multibuffer cryptographic daemon (mcryptd) in the Linux kernel did not properly handle being invoked with incompatible algorithms. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-10147)

 Qidan He discovered that the ICMP implementation in the Linux kernel did not properly check the size of an ICMP header. A local attacker with CAP_NET_ADMIN could use this to expose sensitive information.
 (CVE-2016-8399)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected kernel package.
