high Nessus Plugin ID 93603

Language:

Synopsis

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

Description

USN-3083-1 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 LTS.

Dmitry Vyukov discovered that the IPv6 implementation in the Linux kernel did not properly handle options data, including a use-after-free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2016-3841)

It was discovered that a race condition existed when handling heartbeat- timeout events in the SCTP implementation of the Linux kernel. A remote attacker could use this to cause a denial of service.
(CVE-2015-8767).

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 linux-image-3.13-generic and / or linux-image-3.13-generic-lpae packages.
